Can someone explain why we still need Pt(s) on the left side of the salt bridge even if there is I2(s)? Doesn't I2(s) already act as a conductor?
Thank you!

I think it's because I2, even though it's in its solid state, is a nonmetal. A metal is needed to transfer electrons from the anode to cathode, so Pt(s) has to be used. Hope this helps!
