### 6L.5B

For the cell diagram for the reaction $Ce^{4+}(aq)+I^{-}(aq)\rightarrow I_{2}(s)+Ce^{3+}(aq)$, how do you know that Platinum is included in the cell diagram on both the anode and cathode sides of the diagram?

I believe the condition was if you do not have a solid on either the anode or cathode side, you add it in. I'm not sure why they included platinum on the right side, but on the left side it is included because both molecules are aqueous.
