Q2.During the preparation of hydrogen chloride gas on a humid day, the gas is usu
passed through the guard tube containing calcium chloride. The role of calcium
chloride taken in the guard tube is to:
1. Absorb the evolved gas.
2. Moisten the gas.
3. Absorb moisture from the gas.
4. Absorb Cl–ions from the evolved gas.
Q3.In the following questions, a statement of Assertion is given by the correspond
statement of Reason. Of the statements, mark the correct answer as.
1. If both Assertion and Reason are true and Reason is the correct explanatio
Assertion.
2. If both Assertion and Reason are true, but Reason is not the correct
explanation of Assertion.
3. If Assertion is true, but Reason is false.
4. If Assertion is false, but Reason is true.
5. Both Assertion and Reason are false.
Assertion: The pH of sodium chloride solution is seven.
Reason: Salt of strong acid and a strong base are acidic in nature.
Q4.10mL of a solution of NaOH is found to be completely neutralised by 8mL of
, Q6.Which of the following statements is correct about an aqueous solution of an a
and of a base?
1. Higher the pH, stronger the acid.
2. Higher the pH, weaker the acid.
3. Lower the pH, stronger the base.
4. Lower the pH, weaker the base.

Q7.Sodium hydrogencarbonate when added to acetic acid evolves a gas. Which of
following statements are true about the gas evolved?
1. It turns lime water milky.
2. It extinguishes a burning splinter.
3. It dissolves in a solution of sodium hydroxide.
4. It has a pungent odour.
1. 1 and 2
2. 1, 2 and 3
3. 2, 3 and 4
4. 1 and 4
Q8.If you take some distilled water in a test-tube, add an equal amount of acetic a
to it, shake the test-tube well and leave it undisturbed on the test-tube stand, th
after about 5 minutes, what would you observe?
1. There is a layer of water over the layer of acetic acid.
2. A precipitate is settling at the bottom of the test-tube.
3. Bubbles of colourless gas are coming out of the test-tube.
4. There is a clear, colourless transparent solution in the test-tube.
Q9.An acid (A) with sodium hydrogencarbonate is used in making the cakes fluffy
and spongy. It is due to the release of (B) gas in the reaction. Here, A and B ar
1. A : Oxalic acid : B : CO2
2. A : Tartaric acid : B : O2
3. A : succinic acid : B : H2
4. A : Tartaric acid : B : CO2
Q10.Read the following statements:
1. When a red litmus paper is dipped into reaction mixture of a saponificati
reaction, it turns blue and the reaction is exothermic.
2. When a blue litmus paper is dipped into reaction mixture of a saponificat
reaction, its colour does not change and the reaction is exothermic.
3. When a red litmus paper is dipped into reaction mixture of a saponificati
reaction, its colour does not change and the reaction is endothermic.
4. When a blue litmus paper is dipped into reaction mixture of a saponificat
reaction, its colour does not change and the reaction is endothermic.
