Based on the following electrochemical cell, which statement is true? Half-Reaction Al+ (aq) + 3e Al(s) Cd+ (aq) + 2e Cd(s) Multiple Choice E (V) -1.66 -0.40 %media:chapter18_41.jpg% Al(s) is oxidized and is the cathode. No reaction occurs because Ecell < 0. Al(s) is oxidized and is the anode. Cd(s) is oxidized and is the anode. Cd(s) is oxidized and is the cathode
