WebTake an example of electrolysis of copper (II) sulphate solution using platinum electrodes. By ionic theory, the solution ionizes thus: CuSO 4 (aq) → Cu 2+ (aq) + SO 4 2-(aq) (strong electrolyte) H 2 O⇔ H + + OH – (weak electrolyte) During electrolysis, Cu 2+ and H + ions move to the cathode while SO 4 2-and OH – ions move to the anode.
