Question

During electrolysis of water which gas volume is more and why

Answer 1

During the electrolysis of water Hydrogen gas is liberated at the cathode and Oxygen at the anode.
Here The Volume of Hydrogen will be Twice that of oxygen. Therefore the Ratio of Hydrogen and Oxygen will be

2:1

Equation :-
2H2O(l) –> 2H2(g) + O2(g)

Here u will see 2 parts of Hydrogen this is the volume is more.
