- 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
