Anode |
In a copper-silver electrochemical cell, copper acts as the (1) anode. An anode is the electrode where oxidation takes place. In this case, copper is oxidized to copper ions: \(Cu (s) \longrightarrow Cu^{2+} (aq) + 2e^-\) The electrons released from the oxidation of copper flow through the external circuit to the silver electrode, where they are reduced to silver atoms: \(Ag^+ (aq) + e^- \longrightarrow Ag (s)\) Therefore, the copper electrode is the anode in the copper-silver electrochemical cell. The other options are incorrect:
