The ionic equation for the displacement reaction between magnesium and copper(II) sulfate solution is shown below:
Mg (s)+Cu2+(aq)→Mg2+(aq)+Cu (s) \text{Mg (s)} + \text{Cu}^{2+}\text{(aq)} \rightarrow \text{Mg}^{2+}\text{(aq)} + \text{Cu (s)} Mg (s)+Cu2+(aq)→Mg2+(aq)+Cu (s)This reaction is described as a redox reaction.
Explain, in terms of electrons, which species have been oxidised and which species have been reduced in this reaction.
