Low-grade copper ores can be processed to produce aqueous solutions containing copper(II) ions. Scrap iron is then used to recover the valuable copper metal from these solutions.
Fe(s)+Cu2+(aq)→Fe2+(aq)+Cu(s) \text{Fe}(\text{s}) + \text{Cu}^{2+}(\text{aq}) \rightarrow \text{Fe}^{2+}(\text{aq}) + \text{Cu}(\text{s}) Fe(s)+Cu2+(aq)→Fe2+(aq)+Cu(s)Explain why this displacement reaction is described as a redox reaction. You must refer to electron transfer for both metal species in your answer.
