Genchem Redox Electrochem>Nernst Equation Practice Test

A galvanic cell couples Zn(s)/Zn2+(aq) with Cu(s)/Cu2+(aq) at 25°C. Use the base-10 Nernst form E = E° - (0.0592/n) log Q; E°cell = 1.10 V, with Zn2+ = 1.0 M and Cu2+ = 0.010 M.

A concentration cell is built from two Cu(s)/Cu2+(aq) electrodes at 25°C, one in 1.0 M Cu2+ and the other in 0.010 M Cu2+. Use the base-10 Nernst equation E = (0.0592/n) log(Chigh/Clow) for concentration cells.
