A student adds magnesium to a solution containing silver ions. The student records the species present before and after the reaction.
| Element | Before the reaction | After the reaction |
|---|---|---|
| Magnesium | Mg(s)\text{Mg}(s)Mg(s) | Mg2+(aq)\text{Mg}^{2+}(aq)Mg2+(aq) |
| Silver | Ag+(aq)\text{Ag}^{+}(aq)Ag+(aq) | Ag(s)\text{Ag}(s)Ag(s) |
State which species is reduced and explain how the evidence shows this.
Write the half equation for the reduction that takes place in this reaction.
