A student investigates a displacement reaction by adding solid copper to an aqueous solution of silver nitrate. The ionic equation for the reaction is:
Cu(s)+2Ag+(aq)⟶Cu2+(aq)+2Ag(s) \text{Cu}(\text{s}) + 2\text{Ag}^+(\text{aq}) \longrightarrow \text{Cu}^{2+}(\text{aq}) + 2\text{Ag}(\text{s}) Cu(s)+2Ag+(aq)⟶Cu2+(aq)+2Ag(s)Which species acts as the oxidising agent in this reaction?
Cu(s)\text{Cu}(\text{s})Cu(s)
Ag+(aq)\text{Ag}^+(\text{aq})Ag+(aq)
Cu2+(aq)\text{Cu}^{2+}(\text{aq})Cu2+(aq)
Ag(s)\text{Ag}(\text{s})Ag(s)
