Well, if in this cell oxidation takes place, then our sodium side molecules oh, by the way, these guys are made from sodium solid. So our sodium solid molecules are oxidized, releasing our NA molecules into our solution and releasing electrons into this conductor. These electrons then transfer all the way to this electrode, react with a positively charged ion, which is taken off from the solution into our electrode. They react to produce sodium solid. So really, as our reaction progresses, our concentration of sodium ions increases in beaker one and decreases in beaker two. So, in a way, we can think of our sodium ions traveling from this speaker beaker two to beaker one, from the cathode to the anode.
