### 6L.5 part b)

For $Ce^{4+} + I^{-}\rightarrow I_{2} + Ce^{3+}$, how can you tell that the are in the same solution and therefore need a inert electrode?

Both of the Ce molecules are in the aqueous phase, so they both need an inert electrode.

To tell if you need an inert electrode like platinum, you should be able to tell by looking at the specific matter or state of the equations.
In this specific question, you can see that both Ce and I are aqueous, meaning that they need a solid inert electrode to stabilize the redox reaction.
