          Calculate the cell potential for the following reaction that takes place in an electrochemical cell at 25°C.

Mg(s) | Mg²?(aq, 2.74 M) || Cu²?(aq, 0.0033 M) | Cu(s)

Cu²?(aq) + 2 e? ? Cu(s) E° = +0.34 V
Mg²?(aq) + 2 e? ? Mg(s) E° = -2.37 V

+2.12 V
+2.71 V
-1.94 V
+2.62 V
-2.80 V

Step 1

The half-reactions are: Mg(s) -> Mg2+(aq) + 2e- (oxidation half-reaction) Cu2+(aq) + 2e- -> Cu(s) (reduction half-reaction) The standard reduction potential (E') for the reduction half-reaction is given as +0.34 V. However, the oxidation half-reaction is the Show more…
