Question

In the electrolysis of water the gas obtained at anode is x ml, write the volume of
gas at cathode

Answer 1

Explanation:

Hydrogen and oxygen in water is in the ratio 2:1

Since anode is positive terminal of cell, negative ion formed by electrolysis of water ie. O2- ion go to anode and H+ ion go to cathode

Volume of oxygen at anode = x ml

:. Volume of hydrogen gas at cathode = 2x ml
