Now, this guy actually comes from half cell number two, right? Because when we ask these guys up, this guy from hazel number two will appear on the left side of our net equation while this aqueous copper will appear on the right side of our equation. So we go from a higher concentration from zero five to a lower concentration zero five and that makes sense. So if we were to write the equilibrium constant expression it would be this concentration divided by this concentration and we'll see why that's important in a second. 1st, let's review exactly what happens in this setup. Well, this is the more dilute solution.
