6L.5 part d

Why is the circled Au a solid? Shouldn't it be aqueous bc the Au on the reactant side is aqueous not solid?

Au (s) is the electrode. Even though it is submerged in solution, it has not dissociated and is therefore is solid.

Once Au (s) is oxidized, it becomes aqueous in solution as it loses electrons. Think of it as Au being the electrode, which starts to erode as oxidation occurs.
