Q1. Why is sodium kept immersed in kerosene oil?
Ans:

  • Sodium is a very reactive metal and combines explosively with air(oxygen) at room temperature.
  • It also reacts violently with cold water. Hence, it catches fire if kept in open. 
  • Therefore, to prevent accidental fires and accidents, sodium is stored immersed in kerosene oil.

Q2. Write equations for the reactions of
(a) iron with steam
(b) calcium and potassium with water

Ans: 
(a) Iron reacts with steam to form a magnetic oxide of Fe with the liberation of H2.
3Fe(s) + 4H2O(g) → Fe3O4(s) + 4H2(g)
(b) Calcium reacts with water to form calcium hydroxide and hydrogen.
Ca(s) + 2H2O(I) → Ca(OH)2(aq) + H2(g) 
Potassium reacts with cold water violently immediately with evolution of H2 which catches fire.
2K(s) + 2H2O(I) → 2KOH(aq) + 2H2(g)

Q1. Metallic oxides of zinc, magnesium, and copper were heated with the following metals.
In which cases will you find displacement reactions taking place?
Ans:

Q2. Which metals do not corrode easily?
Ans: The more reactive a metal is, more likely it is to be corroded. Therefore, less reactive metals are less likely to get corroded. This is why gold plating provides high resistance to corrosion. 
Example: Gold, Platinum.

Q3. What are alloys?
Ans: Alloys are homogeneous mixtures of two or more elements. The elements could be two metals or a metal and a non-metal. An alloy is formed by first melting the metal and then dissolving the other elements in it.
Example: Steel is an alloy of iron and carbon.

(b) No displacement
(c) No displacement
(d) Displacement reaction takes place
Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq)+ 2Ag(s)
because copper is more reactive than Ag.

Q2. Which of the following methods is suitable for preventing an iron frying pan from rusting?
(a) Applying grease
(b) Applying paint
(c) Applying a coating of zinc
(d) all of the above

Ans: (c)

Explanation:

  • Greece and paints are organic matter which can burn on heating.
  • So, we do not apply grease or paint on a frying pan to prevent it from rusting. We can prevent it from rusting by applying a coating of zinc.
  • Zinc is more reactive than iron, and hence it does not allow the iron to rust.

Q3. An element reacts with oxygen to give a compound a high melting point. This compound is also soluble in water. The element is likely to be
(a) Calcium
(b) Carbon
(c) Silicon
(d) Iron

(a) zinc is costlier than tin.
(b) zinc has a higher melting point than tin.

(c) zinc is more reactive than tin.
(d) zinc is less reactive than tin.

Ans: (c) Zinc is more reactive than tin; that is why tin is used.
Explanation: Food cans are coated with tin and not with zinc because zinc is above the tin in the reactivity series means more reactive than tin and can react with food elements preserved in it.

Q5. You are given a hammer, a battery, a bulb, wires, and a switch.
(a) How could you use them to distinguish between samples of metals and non-metals?
(b) Assess the usefulness of these tests in distinguishing between metals and non-metals
.
Ans: (a) 

  • Take the sample of metal. Hammer it for a long time. Observe the metal after some time.
  • Take the sample of non-metal and hammer it a little. You will observe that metal changes into sheets on hammering, i.e., it is malleable, whereas non-metal is brittle, and it breaks on hammering.
  • Set the apparatus, as shown in the figure above.
  • Take the sample of metal and put it between the clips. Switch on the current and observe the bulb.
  • Now take the sample of non-metal and insert it between clips. Switch on the current and observe the bulb.
  • You will observe that the bulb glows when current is switched on in the case of metal sample. 
  • The bulb does not glow in case of non-metal sample.
  • This shows metals are good conductors of electricity, whereas non-metals are bad conductors of electricity.

(b) 

  • These two tests can be used to distinguish between metals and non-metals.
  • Hammering can be used in most metals except in the case of sodium, potassium, and lithium.
  • Conduction of electricity can be used in the classification of most of the metals and non-metals except in graphite, which is a non-metallic conductor.


Q6. What are amphoteric oxides? Give two examples of amphoteric oxides.
Ans:

  • The oxides which act as both acidic as well as basic are called amphoteric oxides.
    Example: Al2O3 and ZnO are amphoteric oxides

Q7. Name two metals which will displace hydrogen from dilute acids, and two metals which will not.
Ans: Zn and Al will displace hydrogen from dilute acids because they are more reactive than hydrogen, whereas Cu and Ag cannot displace hydrogen from dilute acids because they are less reactive than hydrogen.
Zn(s) + 2HCl(dil) → ZnCl2(aq) + H2(g)
2Al(s) + 6HCl(dil) → 2AlCl3(aq) + 3H2(g)

Q8. In the electrolytic refining of a metal M, what would you take as the anode, the cathode, and the electrolyte?
Ans: Impure metal acts as an anode, and pure metal acts as a cathode. Soluble salt of metal acts as an electrolyte.

  • When current is passed through the electrolyte, the impure metal from the anode is dissolved in the electrolyte and an equal amount of pure metal from the electrolyte is deposited on the cathode.

Q9. Pratyush took a sulphur powder on a spatula and heated it. He collected the gas evolved by inverting a test tube over it, as shown in the figure below.

(a) What will be the action of gas on:
(i) dry litmus paper?
(ii) moist litmus paper?

(b) Write a balanced chemical equation for the reaction taking place.
Ans: (a) 
(i) There will be no action on dry litmus paper.
(ii) The colour of litmus paper will turn red because sulfur is non-metal, and the oxides of non-metal are acidic in nature.
(b) Chemical Equation for the reaction taking place.
S + O2   → SO2
(Sulphur)              Sulphur dioxide
SO2     +   H2O → H2SO3
(Sulphurous acid)

Q10. State two ways to prevent the rusting of iron.
Ans: Two ways to prevent the rusting of iron are:
(i) Painting

  • Iron articles are painted so that surface does not come in contact with air and water, and it does not get rusted.

(ii) Galvanisation

  • It is a process in which iron particles are coated with zinc metal so as to prevent them from rusting. 
  • Zinc is more reactive than iron; therefore, it loses electrons more readily and prevents iron from rusting.


Q11. What type of oxides are formed when non-metals combine with oxygen?
Ans: Mostly acidic oxides are formed when non-metal combines with oxygen.

Q12. Give reasons.
(a) Platinum, gold, and silver are used to make jewellery.
(b) Sodium, potassium, and lithium are stored under oil.
(c) Aluminium is a highly reactive metal, yet it is used to make utensils for cooking.
(d) Carbonate and sulfide ores are usually converted into oxides during the process of extraction.

Ans:

(a) Platinum, gold, and silver are used to make jewellery because they are:

  • Very lustrous
  • Also, they are very less reactive and do not corrode easily.

(b) Sodium, potassium, and lithium are:

  • Very reactive metals and react very vigorously with air as well as water.
  • Therefore, they are kept immersed in kerosene oil in order to prevent their contact with air and moisture.

(c) Though aluminium is a highly reactive metal, it is resistant to corrosion. 

This is because:

  •  Aluminium reacts with oxygen present in the air to form a thin layer of aluminium oxide. 
  • This oxide layer is very stable and prevents further reaction of aluminium with oxygen. 
  • Also, it is light in weight and a good conductor of heat. Hence, it is used to make cooking utensils.

(d) Carbonate and sulfide ores are usually converted into oxides during the process of extraction because metals can be easily extracted from their oxides rather than from their carbonates and sulfides.

Q13. You must have seen tarnished copper vessels being cleaned with lemon or tamarind juice. Explain why these sour substances are effective in cleaning the vessels.
Ans:

  • Copper reacts with moist carbon dioxide in the air to form copper carbonate, and as a result, the copper vessel loses its shiny brown surface forming a green layer of copper carbonate.
  • The citric acid present in the lemon or tamarind neutralises the basic copper carbonate and dissolves the layer.
  • That is why tarnished copper vessels are cleaned with lemon or tamarind juice to give the surface of the copper vessel its characteristic lustre.

Q14. Differentiate between metal and non-metal on the basis of their chemical properties.
Ans:

Q15. A man went door to door posing as a goldsmith. He promised to bring back the glitter of old and dull gold ornaments. An unsuspecting lady gave a set of gold bangles to him, which he dipped in a particular solution. The bangles sparkled like new, but their weight was reduced drastically. The lady was upset, but after a futile argument, the man beat a hasty retreat. Can you play the detective to find out the nature of the solution he had used?
Ans:

  • The solution he had used was aqua regia, which is a freshly prepared mixture of concentrated hydrochloric acid and concentrated nitric acid in the ratio of 3:1.
  • Aqua regia is one of the few reagents that are able to dissolve gold.
  • When the person claimed to be a goldsmith dipped bangles in aqua regia, some of the gold got dissolved, and hence the weight of the bangles got reduced.

Q16. Give reasons why copper is used to making hot water tanks and not steel (an alloy of iron).
Ans: Copper is used for making hot water tanks because it has excellent thermal conductivity, allowing efficient heat transfer. It is also highly resistant to corrosion, unlike steel, which rusts easily when exposed to water.

Q1. You have been provided with three test tubes. One of them contains distilled water, and the other two contain an acidic solution and a basic solution, respectively. If you are given only red litmus paper, how will you identify the contents of each test tube?
Ans: 

(i) Put the red litmus paper in all the test tubes, turn by turn. The solution which turns red litmus to blue will be a basic solution. The blue litmus paper formed here can now be used to test the acidic solution.

(ii) Put the blue litmus paper obtained above in the remaining two test-tubes, turn-by-turn. The solution which turns the blue litmus paper to red will be the acidic solution.

(iii) The solution which has no effect on any litmus paper will be neutral and hence it will be distilled water.

Q1. Why should curd and sour substances not be kept in brass and copper vessels?
Ans: 
Curd and sour substances should not be kept in brass and copper vessels because these and other sour food-stuffs contain acids which can react with the metal of the vessel to form poisonous metal compounds which can cause food poisoning and affect our health adversely. 


Q2. Which gas is usually liberated when an acid reacts with a metal? Illustrate with an example. How will you test for the presence of this gas?
Ans: 
Usually, hydrogen gas is liberated when an acid reacts with a metal. For example, let us take the reaction between zinc and sulphuric acid.

The reaction of zinc granules with dil. H2SO4 to liberate hydrogen gas which burns with a ‘pop’ sound
(i) Take 5 g of zinc granules in a test tube.
(ii) Set the apparatus, as shown in the diagram.
(iii) Add 20 mL of dil. H2SO4 with the help of a thistle funnel.
(iv) Collect the gas evolved in a gas jar, as shown in the figure.
(v) Observe the colour and odour of the gas.
(vi) Bring a burning matchstick near the gas jar and record your observations.

Observation: A colourless, odourless gas is evolved. It burns explosively with a ‘pop’ sound when a burning matchstick is brought near it, indicating the presence of hydrogen gas. 

The pop sound is because whenever we bring hydrogen in contact with heat it expands , it is so fast that it breaks the sound barrier.

Chemical Reaction: Zn(s) + H2SO4(dil) → ZnSO4(aq) + H2(g)

Q3. Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride.
Ans: 
Calcium carbonate (A), when reacts with hydrochloric acid, produces carbon dioxide gas with effervescence. Carbon dioxide gas is used as a fire extinguisher. Therefore, it extinguishes a burning candle. Hence, the metal compound A is calcium carbonate.

Chemical Reaction: CaCO3(s) + 2HCl(aq) → CaCl2(s)+ CO2 (g) + H2O(l)

Q1. Why do HCl, HNO3, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?
Ans: 
Release of H+ ion in water will make a compound acidic or non-acidic. Acids are substances which, upon dissociating with water, resulting in the production of Hydrogen ions.  HCI, HNO3, etc. dissociate into their ions in the presence of water. They form hydrogen ions (H+). These hydrogen ions combine with H2O to form hydronium ions (H3O+). 
The reaction can be given as follows:
HCl → H+ + Cl
H+ + H2O → H3O+
Similarly, HNO3 → H+ + NO3
H+ + H2O →  H3O+

  • Due to this property, HCl and HNO3 show acidic character in aqueous solutions. On the other hand, alcohol and glucose cannot dissociate in water to form hydrogen ions. Hence, they do not show acidic character.

Q2. Why does an aqueous solution of an acid conduct electricity?
Ans: 
An aqueous solution of acid conducts electricity because of the presence of charged particles called ions in it. When dissolved in water, acids dissociate to form ions. 
Example:
HCl + H2O → Cl + H3O+
These ions are responsible for conducting electricity.

Q3. Why does dry HCl gas not change the colour of the dry litmus paper?
Ans: 
Dry HCl gas do not change the colour of dry litmus paper because:

  • We know that H+ ions of acid change the colour of the litmus. 
  • Dry HCI does not dissociate to give H+ ions. 
  • Acids dissociate to give ions only in the aqueous medium. 
  • Since in this case, neither HCI is in the aqueous form nor is the litmus paper wet, so the colour of the litmus paper does not change.

Q4. While diluting an acid, why is it recommended that the acid should be added to water and not water to the acid?
Ans: 
The process of dissolving an acid in water is highly exothermic. The acid must always be added slowly to water with constant stirring. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause severe burns. The glass container may also break due to excessive heating.

Q5. How is the concentration of hydronium ions (H3O+) affected when a solution of an acid is diluted?
Ans: 

  • When a given amount of acid is added to water, there is a fixed number of hydronium ions per unit volume of the solution.
  • On dilution number of hydronium ions per unit volume decreases and the concentration of hydronium ions (H3O+) decreases and becomes weak.

Q6. How is the concentration of hydroxide ions (OH) affected when excess base is dissolved in a solution of sodium hydroxide?
Ans:

  • The concentration of hydroxide ions (OH) increases when the excess base is dissolved in a solution of sodium hydroxide.
  • The concentration of (OH) Hydroxide ions increases when the excessive base is added to the solution of Sodium Hydroxide as the base itself dissociates to give out OH ions which increase their concentration per unit volume.

Q1. You have two solutions, A and B. The pH of solution A is 6, and the pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of these is acidic, and which one is basic?
Ans: 
Solution A has more H+ ion concentration. A pH value of less than 7 indicates the acidic nature, while greater than 7 indicates the basic nature of a solution. So, solution A is acidic, and solution B is basic.

Q2. What effect does the concentration of H+(aq) ions have on the nature of the solution?
Ans: 
The concentration of H+(aq) can have a varied effect on the nature of the solution. With an increase in H+ ion concentration, the solution becomes more acidic, while a decrease in H+ ion causes an increase in the basicity of the solution.

Q3. Do basic solutions also have H+(aq)  ions? If yes, then why are these basic?
Ans: 
Yes, the basic solution also has H+(aq) ions. However, their concentration is less as compared to the concentration of OH ions that makes the solution basic.

Q4. Under what soil conditions do you think a farmer would treat the soil of his fields with quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate)?
Ans: 
If the farmer finds his soil to be more acidic, then to increase the basicity of the soil, he should treat the soil of his field with quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium carbonate).

Q1. What is the common name of the compound Ca(OCl)2?
Ans: 
Bleaching Powder
Explanation: The compound Ca(OCl)2 is commonly known as bleaching powder. The reason for this common name is due to the compound’s primary use. It is often used as a disinfecting agent and to bleach cotton and linen in the textile industry. The chemical name for this compound is calcium hypochlorite, but it is more widely recognized and referred to as bleaching powder.
Bleaching powder structural formula

Q2. Name the substance which on treatment with chlorine yields bleaching powder?
Ans: 
Dry slaked lime [Ca(OH)2].

Explanation: Bleaching powder, also known as Calcium hypochlorite [Ca(OCl)2], is produced by the action of chlorine on dry slaked lime [Ca(OH)2]. This reaction can be represented by the following chemical equation:

2Ca(OH)2 + 2Cl2 → Ca(OCl)2 + CaCl2 + 2H2O

In this reaction, chlorine (Cl2) is added to dry slaked lime (Ca(OH)2) to produce bleaching powder (Ca(OCl)2), calcium chloride (CaCl2), and water (H2O). The chlorine oxidizes the calcium hydroxide to produce the calcium hypochlorite, which is the main component of bleaching powder. The calcium chloride is a byproduct of this reaction.

So, the substance which on treatment with chlorine yields bleaching powder is dry slaked lime [Ca(OH)2].


Q3. Name the sodium compound which is used for softening hard water.
Ans: 
Washing soda (Na2CO3.10H2O)

Explanation: Hard water contains minerals like calcium and magnesium that can cause a buildup in plumbing and appliances, and make it difficult for soap to lather. Sodium carbonate, also known as washing soda or soda ash, is used to soften hard water. When added to water, it reacts with the calcium and magnesium ions, forming insoluble precipitates that can be removed from the water. This reduces the mineral content of the water, effectively “softening” it. The formula Na2CO3.10H2O represents washing soda, which means it is a hydrated salt with 10 molecules of water of crystallization.

Q4. What will happen if a solution of sodium hydro carbonate is heated? Give the equation of the reaction involved.
Ans: 
When sodium hydrogen carbonate is heated, then sodium carbonate and water are formed along with carbon dioxide gas evolution.

(a) 4 mL
(b) 8mL
(c) 12 mL 
(d) 16 mL
Ans: (d) 
Solution:
∴ 10 mL of NaOH will neutralise
= 8 mL of HCI.
= 20 mL of NaOH will neutralise
= 8/10 x 20 = 16 mL.

Q6. Compounds such as alcohols and glucose also contain hydrogen but are not categorized as acids. Describe an activity to prove it.
Ans:

  • Fix two iron nails on a cork and place this cork in a beaker.
  • Connect the nails to the two terminals of a 6-volt battery through a switch and a bulb, as shown in the figure.
  • Now add some dilute hydrochloric acid in the beaker and switch on the current. Take the observation.
  • Repeat the experiment separately with alcohol and glucose solution.

Observation: You will observe that in the case of dilute hydrochloric acid bulb glows, but when glucose or alcohol solution is taken in the beaker, the bulb does not glow.
Conclusion: The aqueous solution of hydrochloric acid conducts electricity due to the presence of types of charged particles: Hydrogen ions and chloride ions. Unlike acids glucose and ethanol do not ionise in an aqueous solution, i.e. they do not give H+ ions; therefore, they cannot conduct electricity. Thus, glucose and ethanol are not categorized as acids.

Q7. Why does distilled water not conduct electricity, whereas rainwater does? 

Ans: 

  • Distilled water does not conduct electricity because it does not contain any ionic compound (like acids, bases or salts) dissolved in it.
  • Rainwater, while falling to the earth through the atmosphere, dissolves an acidic gas carbon dioxide from the air and forms carbonic acid (H2CO3). 
  • Carbonic acid provides hydrogen ions, H+ (aq) and carbonate ions, CO(aq)32to rainwater. 
  • Hence, due to the presence of carbonic acid which provides ions to rainwater, the rainwater conducts electricity.

Q8. Why do acids not show acidic behaviour in the absence of water?
Ans: 
It is because acids do not dissociate into ions in the absence of water. But when an acid is dissolved in water, it forms hydrogen ions and hence, shows acidic behaviour.

Q9. Five solutions A, B, C, D and E when tested with universal indicator showed pH as 4, 1, 11, 7 and 9, respectively. Which solution is

Q10. Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrochloric acid (HCl) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. In which test tube will the fizzing occur more vigorously and why?
Ans: 
Fizzing will occur more vigorously in test tube A. Hydrochloric acid (HCl) is a strong acid whereas acetic acid (CH3COOH) is a weak acid. Being strong acid, the hydrochloric acid solution contains a much greater amount of hydrogen ions in it due to which the fizzing will occur more vigorously in test tube A (containing hydrochloric acid). The fizzing is due to the evolution of hydrogen gas which is formed by the action of acid on the magnesium metal of magnesium ribbon.

Q11. Fresh milk has a pH of 6. How do you think the pH will change as it turns into curd? Explain your answer.
Ans: 
Milk contains carbohydrate lactose. When milk sets into curd, lactose gets converted into an acid called lactic acid. Due to the formation of lactic acid, the pH of milk falls below 6.

Q12. A milkman adds a very small amount of baking soda to fresh milk.
(a) Why does he shift the pH of the fresh milk from 6 to slightly alkaline?
(b) Why does this milk take a long time to set as curd?

Ans: 
(a) The milkman shifts the pH of the fresh milk from 6 to slightly alkaline because, in alkaline conditions, milk does not set as curd easily.

Double displacement reaction: Those reactions in which two compounds exchange their ions to form two new compounds are called double displacement reactions.
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

Q.14. In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal. Write down the reaction involved.
Ans: Cu(s) + 2AgNO3(aq) → Cu(NO3)2(aq) + 2Ag(s)

Q.15. What do you mean by a precipitation reaction? Explain by giving examples.
Ans: When two solutions containing soluble salts are combined, a double displacement reaction takes place in which the ions are exchanged between the compounds. When one of such compounds is formed  in solid form (that is insoluble in aqua) then it settles down at the bottom of the container. This solid is known as the precipitate and the respective reaction is termed as the precipitation reaction. Few examples of precipitation reactions are:
When solutions of silver nitrate and sodium chloride are mixed, white precipitate of silver chloride is formed.
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

On adding dilute hydrochloric acid to the aqueous solution of lead nitrate, precipitate of lead chloride is formed.
Pb(NO3)2 + 2HCl → PbCl2 + 2HNO3

Ans: ‘X’ is Copper.
Copper gets oxidised to copper oxide which is black in colour.
2Cu(s) + O2(g) → 2CuO(s) (Heat)

Q.18. Why do we apply paint on iron articles? 
Ans: Painting is done so as to prevent iron from rusting. When the surface of iron is coated with paint, its surface does not come in contact with oxygen and moisture and therefore, rusting does not take place.

Q.19. Oil and fat containing food items are flushed with nitrogen. Why?
Ans: The main purpose of flushing Nitrogen into food packets that contain oil and fat items is to prevent Rancidity which occurs when the oil or fat reacts with the oxygen letting out an unpleasant smell and taste. Therefore by flushing Nitrogen, an unreactive surrounding is created thus preventing rancidity.
Variety of Oils

Q.20. Explain the following terms with one example each.
(a) Corrosion
(b) Rancidity

Ans: (a) Corrosion: It is the process in which metals are slowly eaten up by the action of air moisture or chemicals. For example rusting is a form of corrosion in which iron is eaten up by the action of air and moisture and a reddish brown coating of iron oxide is formed as shown in the following chemical reaction.
2Fe + 3H2O → Fe2O3 + 3H2
(b) Rancidity: When the substance containing oils and fats are exposed to air they get oxidised and become rancid due to which their smell, taste and colour change. This process is known as rancidity. For example when a when butter is kept open for a long time then its smell and taste gets changed.
