Question

In the electrolysis of water, [3](a)name the gas collected at the anode and the cathode.(b)why is the volume of the gas collected at one electrode double than that collected at the other

Answer 1

$at \: cathode \: : hydrogen \\ at \: anode : oxygen \\ the \: volume \: of \: hydrogen \: gas \\ collected \: at \: cathode \: is \: more \\ than \: volume \: of \: oxygen \: gas \: at \\ anode \: because \: water \: is \: made \: up \\ of \: 2 \: parts \: of \: hydrogen \: and \: 1 \\ part \: of \: oxygen \: by \: volume$

This may help you very much

Answer 2

Answer:

In electrolysis of water :

a ) . Hydrogen gas collected at cathode. And oxygen gas gas collect at anode.

b ) . We know that in water there is 2 hydrogen atom and 1 oxygen atom. That's why volume of gas collected at one electrode double than the other.

c ) . Pure water is a bad conductor of electricity when we add drops of dil sulphuric acid we make it a good conductor of electricity.
