Electrochemistry - Standart Potential
1. For the voltaic cell shown, calculate theEocell.
St. Red. Pot. (V)
Hg2Cl2/Hg
0.34
Cu2+/Cu+
0.16
Hg(l), Hg2Cl2(s) l Cl-(aq) llCu2+(aq), Cu+(aq) l Pt(s)
2. Calculate the standard emf for a voltaic cell whose cellreaction is represented by the balanced equation.
St. Red. Pot. (V)
Pb2+/Pb
-0.13
Zn2+/Zn
-0.76
Pb(s) + Zn2+(aq) → Pb2+(aq) + Zn(s)
3. For the galvanic cell shown,calculate theEo.
St. Red. Pot. (V)
AuCl4-/Au
0.99
F2/F-2.87
Au(s) l AuCl4-(aq), Cl-(aq) llF2(g) l F-(aq) l Pt(s)
