Now, this guy cadmium ion goes from an ion to a neutral charge, and that means this guy is reduced. So it's the oxidizing agent. It gains those electrons that are released by this zinc solid metal. So that means in step two, when we draw our electrochemical cell, the first half cell will contain our zinc solid. And that's because zinc is oxidized, and the anode always contains the oxidation reaction. So this is our zinc metal.
