Answer:
The balanced chemical equation for the electrolysis of water is
2H2O-------->2H2+O2
It can be observed from the balanced chemical equation that the volumes of hydrogen and oxygen produced during electrolysis are in the ratio 2:1. Thus, the volume of hydrogen gas collected in the process is double than that of oxygen.
