Question 33:Write the reaction occurring at anode and cathode and the products of electrolysis of aq KCl. The correct answer is - The electrolysis of aqueous KCl produces hydrogen gas at the cathode and chlorine gas at the anode. The overall reaction is: 2H2O(l) + 2e- -> H2(g) + 2OH-(aq) (cathode half-reaction) 2Cl-(aq) -> Cl2(g) + 2e- (anode half-reaction) The net ionic equation for the electrolysis of aqueous KCl is: 2H2O(l) + 2Cl-(aq) -> H2(g) + Cl2(g) + 2OH-(aq) So, the products of the electrolysis of aqueous KCl are hydrogen gas and chlorine gas.
