Question

Electrolysis of water is a decomposition reaction. The mole ratio of hydrogen and oxygen

gases liberated during electrolysis of water is :

(a) 1:1 (b) 2:1 (c) 4:1 (d) 1:2​

Answer 1

Answer:

The molecular formula of water is H2O. It contains two atoms of hydrogen and one atom of oxygen. Hence the molar ratio of hydrogen and oxygen gases liberated during electrolysis of water is 2:1
