Q. During the electrolysis of acidified water, where would oxygen and hydrogen gas be liberated?

Q. Water contains 88.89% of A by weight is decomposed into its elements B and oxygen. Pure C is a poor conductor of electricity and hence it is acidified using dilute sulphuric acid. When an electric current is passed through acidulated water, using platinum electrons, hydrogen gas is evolved at cathode and oxygen gas is evolved at D.

What is A?
