Question 1

Of Sn²⁺, Ag⁺, and/or Zn²⁺, which could be reduced by Cu?

◦ Sn²⁺

◦ Ag⁺

◦ Zn²⁺

◦ Two of them could be reduced by Cu.
◦ All of them could be reduced by Cu.

Question 2

Refer to the galvanic cell below (the contents of each half-cell are written beneath each compartment):

0.10 M MnO₄^– 0.40 M Cr³⁺
0.20 M Mn²⁺ 0.30 M Cr₂O₇^2–
0.010 M H⁺ 0.010 M H⁺
The standard reduction potentials are as follows:
MnO₄^– + 8H⁺ + 5e^–→ Mn²⁺ + 4H₂O, E° = 1.51 V
Cr₂O₇^2– + 14H⁺ + 6e^–→ 2Cr³⁺ + 7H₂O, E° = 1.33 V

When current is allowed to flow, which species is oxidized?

Reference: 18-3

◦ Cr₂O₇^2–
◦ Cr³⁺
◦ MnO₄^–
◦ Mn²⁺
◦ H⁺
