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.
