Question

Why the amount of to gas liberated at
cathode is twice the volume of gas liberated
at anode during electrolytic decomposition of water]​

Answer 1

Hii there:))

when water undergoes electrolysis, it decomposes into hydrogen and oxygen.

The chemical formula of water is H2O, which indicates that for every  atom of oxygen there are  atoms of H, quite the double.

hydrogen is a positive gas and is hence attracted to the cathode whereas oxygen being negative is attracted to the positive anode.

hence, we may say that the gas at cathode is twice the amount of gas at anode as hydrogen liberated is twice the amount of oxygen liberATED

hope this helps:))

please mark this as the brainliest;)
