Consider a galvanic electrochemical
cell constructed using Cr/Cr3* and
Zn/Zn2* at 25 °C. The following half-
reactions are provided for each
metal:
Cr3+ (aq) + 3 e- → Cr(s) E°red =
-0.744 V
Zn2+(aq) + 2 e- → Zn(s) E°red =
-0.763 V
Write the balanced equation for the
overall reaction in acidic solution.
Zn* (aq) + Cr* (aq) → 2 Zn(s) + 3 Cr (s)
