Most ionic salts can be used satisfactorily in electrolysis. Concentrations of 1M or less are
suitable. Potassium iodide gives iodine at the anode and hydrogen gas at the cathode. Zinc
sulphate gives a spongy mass of zinc at the cathode, oxygen gas at the anode. Lead acetate
deposits lead on the cathode and oxygen gas is produced at the anode. If the lead acetate
solution is cloudy, add a few drops of acetic acid. Sodium chloride gives hydrogen gas at the
cathode and chlorine gas at the anode. Copper sulphate deposits copper at the cathode and
oxygen gas is produced at the anode.
