Question

In the electrolysis of water name the gas collected at cathode and anode,why is he volume of gas collected at 1 electron double than the other,what could happen dilute h2so4 is not added to water

Answer 1

At anode oxygen gas collected
At cathode Hydrogen gas collected

We pour h2so4 in water because it make water conducting.

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.
