What happens during electrolysis?

Electrolysis is the decomposition of an ionic compound by passing an electric current through it. For electrolysis of a molten ionic compound, the compound is heated until it melts so that its ions are free to move. In a solid ionic compound, the ions are fixed in place and cannot move and therefore cannot carry an electric current.
