  • Electrolysis of Aqueous Solution
    • Will be ionic compound ions, hydrogen and hydroxide ions
    • Anode. If OH- and halide ions are present molecules of chlorine, bromine or iodine will be formed. NO HALIDE= OH DISCHARGED AND OXYGEN FORMED
    • Chlorine ions causes chlorine gas to be formed
    • Cathode. If H+ ions and metal ions present. Metal more reactive than hydrogen causes hydrogen gas. Less reactive causes solid layer of pure metal
    • Chlorine bleaches litmus paper and turns it white
    • Hydrogen= squeaky pop with a lighted splint
    • Oxygen will  relight a glowing splint
