Question

During electrolysis of water gas collected in one test tube is double than other why name the gas collected at cathode and anode why few drops of Dil H2So4 is added to water during electrolysis

Answer 1

Explanation:

the gas collected in one test tube is duble the other because on electrolysis H2O is converted into H2 +O2.

so H2O contains two parts of hydrogen and only one part of oxygen

sulphuric avid is added so that electricity could easily be passed through water

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.
