in electrolysis of water why is the volume of gas collected over one electrode double that of gas collected over the other electrode
Answers
Answer:
Explanation:
Molecular formula of water is H2O therefore it has 2 parts of hydrogen and one part of oxygen .
Hydrogen being positively charged, is obtained at the cathode( which is negatively charged).
And oxygen being negatively charged gets deposited on anode(which is positively charged)...
That's why after electrolysis of water,the volume of gas collected at cathode is double than the volume of gas at anode.....
Hope it helps....
Thank you
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.
