WebElectrolysis (Part 5) Electrolysis of water / acidified water / dilute sulphuric acid ICSE- 10 WebApr 7, 2024 · Water dissociates to a very small extent as water is a weak electrolyte. The dissociation of water gives hydronium ions (protons) and hydroxide ions. Sulphuric acid is a strong acid. It completely dissociates in aqueous solution to provide protons and sulphate ions. Thus, the solution contains protons, hydroxide ions and sulphate ions.
