1. An electrochemical cell is based on the following two
half-reactions:
Ox: Pb(s)→Pb2+(aq, 0.18 M )+2e−
Red: MnO−4(aq, 1.50 M )+4H+(aq,
1.8 M )+3e−→
MnO2(s)+2H2O(l) Compute the cell potential at 25
∘C.
2.A concentration cell consists of two Sn/Sn2+ half-cells. The
cell has a potential of 0.16 V at 25 ∘C.
What is the ratio of the Sn2+ concentrations in the two
half-cells?
Express your answer using two significant figures.
3.Metal plating is done by passing current through a metal...
