Single Replacement Reactions, Pt+ZnSO4?

Question

I need help on this formula problem. I'm not sure if from Pt+ZnSO4 the answer would be either Zinc Platinum (IV) Sulfate or Zinc (II) Platinum (IV) Sulfate since the charge is cancelled for Zinc. Which one is it?
Thanks.

I just have to find out if the calculations are right, we aren't learning yet if the solution is able to made or not, just how to use the Single Replacement formulas.

Answer 1

In a single replacement reaction, the more active metal will replace the less active one. Such as:

CuSO4 (aq) + Zn (s) ----> ZnSO4 + Cu (s)

To the best of my knowledge, Platinum will not replace Zinc in a sulfate solution:

ZnSO4 (aq) + Pt (s) ----> ZnSO4 (aq) + Pt (s) [No Reaction]

Platinum is often used as an electrode because it is difficult to replace by direct single replacement reactions.
