Chapter 17, Problem 76QAP

Consider a cell in which the reaction is
$\text{Pb}\left(s\right)+2{\text{H}}^{+}\left(aq\right)\to {\text{Pb}}^{2+}\left(aq\right)+{\text{H}}_2\left(g\right)$
(a) Calculate E° for this cell.
(b) Chloride ions are added to the $\text{Pb}|{\text{Pb}}^{2+}$ half-cell to precipitate PbCl₂. The voltage is measured to be +0.210 V. Taking $\left[{\text{H}}^{+}\right]=1.0$M, and $P_{{\text{H}}_2}=1.0$ atm, calculate [Pb²⁺].
(c) Taking [Cl^-] in (b) to be 0.10 M, calculate K_spof PbCl₂.
