Question

In electrolysis of water
a) name the gas collected at anode and cathode
b) why is the volume of gas collected at one electrode double than the other
c)what would happen if did.H²SO⁴ is not added to water?

Answer 1

a) Oxygen is collected at anode and Hydrogen is collected at cathode
b) volume of gas collevted at electrode is double than the other coz in electrolysis of water there is 2 molecules of hydrogen presenr.
c) if it is not added in water so water will not be diffused in hydrogen and oxygen

hope you like it.

Answer 2

at anode oxygen gas and at cathode hydrogen gas
the volume of gas collected at one electrode is double than the other as more it liberates than the other electrode
if sulphuric acid is not added the reaction may be slower bcoz we are adding sulphuric acid to faster the rate of reaction
