During the electrolysis of water
(a) Name the gas collected at the anode and cathode
(b) Why it is the volume of gas collected at one electrode double that collected at the other
(c) what would happen if dilute H2SO4 is not added to water
Answers
1.the gas collected at annode is oxygen and the gas collected at cathode is hydrogen.
2.Hydrogen is in double amount because hydrogen and oxygen always combine in the ratio 2:1.The mass amount of hydrogen is greater that is 2.
3.it will not be conductive that is it will not conduct electricity.Distilled water does not conduct electricity if few drops of H2SO4 are not added.
Hope it will help 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.
