Quizplus · Accepted Answer

In electrochemical cells, oxidation occurs at the anode and reduction occurs at the cathode. Based on the given half-reactions, Al has a higher reduction potential than Cd, which means it is more likely to be reduced than Cd. Therefore, Cd is the reducing agent and Al is the oxidizing agent. This means that Al will lose electrons and undergo oxidation at the anode while Cd will gain electrons and undergo reduction at the cathode. The anode is always where oxidation occurs, so Al(s) is the anode.
