Question

In the electrolysis of water, a) Name the gas collected at anode and cathode b) Why is the volume of gas collected at one electrode double than the other? Name this gas

Answer 1

during the electrolysis of water the hydrogen gets collected at the cathode and oxygen gets collected at the anode so..
H2O=H2 + O2
after balancing, we get
2H2O= 2H2 + O2
hence gas collected at one electrode is double the other

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.
