How ionic solutions carry current. Resistance and conductivity, molar conductivity and how it changes with concentration, and Kohlrausch's law for strong and weak electrolytes.
What happens at the electrodes during electrolysis and how much product forms, by Faraday's laws. Then primary and secondary batteries, fuel cells and the corrosion of iron.
