You add Pt to the side that doesn't have a solid.

In the sixth edition, for question 14.13, they added platinum to both sides even though I2 (s) was present on one side?

So, the Pt is added if there is not a solid on either one or both sides. But, you add it to both sides even if one side already has a solid conductor.

I2 is not a metal, and therefore it cannot act as a conductor. Because of this, you will need platinum.

On the side with no solid metal on it. The platinum will be used to replace the missing solid metal needed for the reaction to proceed.
