SOLVED:The following concentrations are found in mixtures of ions in equilibrium with slightly soluble solids. From the concentrations given, calculate K_{\mathrm{sp}} for each of the slightly soluble solids indicated: (a) TICl: [\mathrm{T}]^{+} ]=1.21 \times 10^{-2} \mathrm{M},\left[\mathrm{Cl}^{-}\right]=1.2 \times 10^{-2} \mathrm{M} (b) \mathrm{Ce}\left(\mathrm{IO}_{3}\right)_{4} :\left[\mathrm{Ce}^{4+}\right]=1.8 \times 10^{-4} M,\left[\mathrm{IO}_{3}^{-}\right]=2.6 \times 10^{-13} \mathrm{M} (c) \mathrm{Gd}_{2}\left(\mathrm{SO}_{4}\right)_{3} :\left[\mathrm{Gd}^{3+}\right]=0.132 \mathrm{M},\left[\mathrm{SO}_{4}^{2-}\right]=0.198 \mathrm{M} (d) \mathrm{Ag}_{2} \mathrm{SO}_{4} :\left[\mathrm{Ag}^{+}\right]=2.40 \times 10^{-2} M,\left[\mathrm{SO}_{4}^{2-}\right]=2.05 \times 10^{-2} \mathrm{M} (e) \mathrm{BaSO}_{4} :\left[\mathrm{Ba}^{2+}\right]=0.500 \mathrm{M},\left[\mathrm{SO}_{4}^{2-}\right]=2.16 \times 10^{-10} \mathrm{M}
