The ionic equation for the reaction between zinc and aqueous copper ions is given below. $\text{Zn}(s) + \text{Cu}^{2+}(aq) \rightarrow \text{Zn}^{2+}(aq) + \text{Cu}(s)$ Which statement about this reaction is correct?
- ACopper ions are oxidised and their oxidation state changes.
- BCopper ions are reduced because they lose electrons.
- CZinc atoms are oxidised and their oxidation state changes.
- DZinc atoms are reduced because they gain electrons.
