Question

In the electrolysis of water name the gas collected at anode and cathode why is the volume of gas collected at one electrode double than the other what would happen if dilute sulphuric acid is not added to water

Answer 1

Answer:

gas at anode  -  O2

gas at cathode - h2

Explanation:

the volume of gas at the cathode is double that of the gas at the anode because 2 molecules of water give 2 molecules of hydrogen gas and 1 molecule of oxygen gas.

           ELECTROLYSIS

2H20 --------------------------> 2H2 + O2

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.
