Why do we use sulphuric acid for the electrolysis of water and not any other acid like nitric acid or sulphuric acid?

Dear student!

Alone water molecule (pure) is a bad conductor of electricity and so it could not be electrolyzed and so the sulphuric acid is mixed which produces H⁺ ion when mixed in water an so it increases the charge and so the conductance of the water increases which make the reaction faster.
