Show that in qualitative cation analysis group $1,$ if you obtain $1.00 \mathrm{mL}$ of saturated $\mathrm{PbCl}_{2}(\mathrm{aq})$ at $25^{\circ} \mathrm{C}$ sufficient $\mathrm{Pb}^{2+}$ should be present to produce a precipitate of $\mathrm{PbCrO}_{4}(\mathrm{s}) .$ Assume that you use $1 \mathrm{drop}$ $(0.05 \mathrm{mL})$ of $1.0 \mathrm{M} \mathrm{K}_{2} \mathrm{CrO}_{4}$ for the test.
A mixture contains $1.0 \times 10^{-3} M \mathrm{Cu}^{2+}$ and $1.0 \times 10^{-3} M$ $\mathrm{Mn}^{2+}$ and is saturated with 0.10$M \mathrm{H}_{2} \mathrm{S} .$ Determine a pH where CuS precipitates but MnS does not precipitate. $K_{\mathrm{sp}}$ for $\mathrm{CuS}=8.5 \times 10^{-45}$ and $K_{\mathrm{sp}} \mathrm{for} \mathrm{MnS}=2.3 \times 10^{-13} .$
Copper(I) ions in aqueous solution react with $\mathrm{NH}_{3}(a q)$ at $25^{\circ} \mathrm{C}$ according to $$ \begin{array}{r} \mathrm{Cu}^{+}(a q)+2 \mathrm{NH}_{3}(a q) \leftrightharpoons\left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{2}\right]^{+}(a q) \\ K_{\mathrm{f}}=6.3 \times 10^{10} \mathrm{M}^{-2} \end{array} $$ Calculate the solubility of $\operatorname{CuBr}(s)$ in a solution in which the equilibrium concentration of $\mathrm{NH}_{3}(a q)$ is $0.15 \mathrm{M}$ at $25^{\circ} \mathrm{C}$.
