And by definition, wherever reduction occurs, that's our cathode. So this side of the cell is our cathode, and that means this side of the cell is the amo, because that's where oxidation takes place. The chloride ions are oxidized and lose electrons, and these electrons jump into the electrode and travel on to this way, thus creating a circuit that moves in this direction. Now, now that we know what our layout of our electrolytic cell is, let's talk about the oxidation and reduction reactions. Now, when we spoke about molten sodium chloride, only one oxidation reaction was possible, and only one reduction reaction was possible. But now we're in the presence of a solvent, namely water.
