Question

When solid Fe metal is put into an aqueous solution of SnSO4, solid Sn metal and a solution of FeSO4 result. Write the net ionic equation for the reaction.

Answer 1

Answer:Fe(s) + Sn^2+(aq) ----> Fe^2+(aq) + Sn(s)

Explanation:

The net ionic equation involved is;

Fe(s) + Sn^2+(aq) ----> Fe^2+(aq) + Sn(s)

We must recall that iron is above tin in the electrochemical series. The implication of this is that, iron has a more negative reduction potential compared to tin.

A metal can displace metals below it in the electrochemical series from their aqeous solution. Hence, iron displaces tin from it's solution.
