What is the net ionic equation for the reaction of solid iron with aqueous copper sulfate? (Hint: First use the activity series to write the formula unit equation!) 1. 2 Fe (s) + 3 CuSO4 (aq) → Fe2 (SO4) 3 (s) + 3 Cu (s) 2. 2 Fe (s) + 3 Cu2 + (aq) + 3 SO2 - 4 (aq) → Fe2 (SO4) 3 (s) + 3 Cu (s) 3. No reaction occurs. 4. 2 Fe (s) + 3 CuSO4 (aq) → Fe2 (SO4) 3 (aq) + 3 Cu (s) 5. 2 Fe (s) + 3 Cu2 + (aq) + 3 SO2 - 4 (aq) → 2 Fe3 + (aq) + 3 SO2 - 4 (aq) + 3 Cu (s) 6. 2 Fe (s) + 3 Cu2 + (aq) → 2 Fe3 + (aq) + 3 Cu (s)

6. 2 Fe (s) + 3 Cu2 + (aq) → 2 Fe3 + (aq) + 3 Cu (s).

Explanation:

The reaction of solid iron with aqueous copper sulfate is an example of a single displacement type of reaction.

Half equations

2 Fe (s) → 2Fe2 + (aq)

3CuSO4 (aq) → 3Cu (s) + 3SO4^2 - (aq)

Net ionic equation:

2Fe (s) + 3Cu2 + (aq) → Fe2 + (s) + 3Cu (aq)

2Fe (s) + 3CuSO4 (aq) → Fe2 (SO4) 3 (s) + 3Cu2 + (aq)
