18. A voltaic cell is constructed by immersing a strip of copper metal in 1.0 MCuSO4 solution and a strip of aluminum in 0.50 M Al2(SO4)3 solution. A wire and a salt bridge complete the circuit. The aluminum strip loses mass, and the concentration of aluminum ions in the solution increases. The copper electrode gains mass and the concentration of copper ions decreases. Which of the following are applicable to the copper electrode?
I. The anode II. The cathode III. The positive electrode IV. The electrode at which electrons are produced V. The negative electrode VI. The electrode at which electrons are used up
(A) I, III, and V
(B) I, IV, and V
(C) II, III, and VI
(D) II, IV, and VI
(E) None of the first four responses contains all the correct choices and no others
