Question

In the electrolysis of water why the volume of gas collected at one electrode doubled than the other

Answer 1

The water is formed by combination of two hydrogen atoms and one oxygen atom . So on the electrolysis of water the hydrogen forms its molecule while oxygen remains single . So the volume of gas obtained is on the ratio two is to one, two for hydrogen and one for oxygen.

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.
