17.4 Exercise 5

Use the data in Appendix L to calculate equilibrium constants for the following reactions. Assume 298.15 K if no temperature is given.

(a) $\text{AgCl} \left(s\right) \rightleftharpoons \text{Ag}^{+} \left(a q\right) + \text{Cl}^{−} \left(a q\right)$

(b) $\text{CdS} \left(s\right) \rightleftharpoons \text{Cd}^{2+} \left(a q\right) + \text{S}^{2−} \left(a q\right) \text{at 377 K}$

(c) $\text{Hg}^{2+} \left(a q\right) + 4 \text{Br}^{−} \left(a q\right) \rightleftharpoons \left[\text{HgBr}_{4}\right]^{2−} \left(a q\right)$

(d) $\text{H}_{2} \text{O} \left(l\right) \rightleftharpoons \text{H}^{+} \left(a q\right) + \text{OH}^{−} \left(a q\right) \text{at 25} °C$
