Question

Assertion: During the electrolysis of water, the ratio of volumes of hydrogen and oxygen gases produced is 2:1. Reason:For everyone volume of oxygen produced at anode,two volumes of hydrogen is produced at cathode: 2H2O  2H2 + O2 (a) Both A and R are true, and R is correct explanation of the assertion. (b) Both A and R are true, but R is not the correct explanation of the assertion. (c) A is true, but R is false. (a) A is false, but R is true.​

Answer 1

Answer:

a) A is false, but R is true.

Answer 2

Explanation:

So, electrolysis of water produces 2 volumes of hydrogen gas and 1 volume of oxygen gas because the ratio of hydrogen and oxygen elements in water is 2:1 by volume. Therefore, the amount of gases collected in two test tubes is not equal.
