Consider a voltaic cell that is set up as follows: Anode contains a Zn(s) electrode and 1M Zn2+(aq) Cathode contains a Pt(s) electrode and 1M MnO4–(aq), Mn2+(aq), and H+(aq) Which of the following statements match the cathode?
a. The electrode increases in mass
b. Oxidation occurs at this half-cell
c. Electrons enter the half-cell
d. The electrode is inactive
e. Cations from the salt-bridge move to this half-cell
f. The electrode is negative
