1. The electrolyte is the molten ionic solid or solution of ions. Electrolysis is only used on ionic compounds.
2. Anions and they are attracted to the positive electrode - the anode. Cations are positively charged and attracted to the negative electrode - the cathode.
3. Graphite or platinum - because they are unreactive substances.
4. Oxidation Is Loss (of electrons). Reduction Is Gain.
5. Hydrogen may be produced at the cathode if the other positive ions are of metals more reactive than hydrogen. Essentially, if two elements can be produced at an electrode, the less reactive element will be formed.
6. Chlorine, Iodine, Bromine, Oxygen
