1.	What happens when a piece of copper is added to (a) an aq solution of FeSO4 (b) an Aq solution of FeCl3?
Answer» a. Nothing will happen when the piece of copper is added to FeSO₄ because reduction potential E⁰Cu₂/Cu(0.34) is more than the reduction potential E⁰(Fe²⁺/Fe) (0.44 V). b. Copper will dissolve in an aq solution of FeCl₃ because reduction potential E⁰ Fe³⁺/Fe²⁺(0.77 V) is more than the reduction potential of E⁰ Cu²/Cu(0.34) Cu(s) + 2FeCl₃ (aq) → Cu₂(aq) + 2FeCl₂(aq)

Answer»

a. Nothing will happen when the piece of copper is added to FeSO₄ because reduction potential E⁰Cu₂/Cu(0.34) is more than the reduction potential E⁰(Fe²⁺/Fe) (0.44 V).

b. Copper will dissolve in an aq solution of FeCl₃ because reduction potential E⁰ Fe³⁺/Fe²⁺(0.77 V) is more than the reduction potential of E⁰ Cu²/Cu(0.34)

Cu(s) + 2FeCl₃ (aq) → Cu₂(aq) + 2FeCl₂(aq)
