Options

1. AWhen equal volumes of a solution containing $\mathrm{Sr}^{2+}$ ( 0.01 M ) and another containing $\mathrm{F}^{-}(0.001 \mathrm{M})$ are mixed at $25^{{}^{{}^{\circ}}} \mathrm{C}, \mathrm{SrF}_2$ will be precipitated \left(\mathrm{K}_{\mathrm{sp}}\right.$of$\mathrm{SrF}_2=8.0 \times 10^{-10}$at \left.25^{{}^{{}^{\circ}}} \mathrm{C}\right)$
2. BWhen equal volumes of a solution containing \mathrm{Ba}^{2+} \left(1.0 $\times$10^{-4} \mathrm{M}\right) and another containing\mathrm{F}^{-} \left(1.0 \times 10^{-2} \mathrm{M}\right)$are mixed at$25^{{}^{{}^{\circ}}} \mathrm{C}, \mathrm{BaF}_2$will be precipitated \left(\mathrm{K}_{\mathrm{sp}}\right.$ of $\mathrm{BaF}_2=1.0 \times 10^{-6}$ at \left.25^{{}^{{}^{\circ}}} \mathrm{C}\right)
3. CThe solubility product \left(\mathrm{K}_{\mathrm{sp}}\right) and the molar solubility $(\mathrm{s})$ of $\mathrm{La}\left(\mathrm{IO}_3\right)_3$ are related as $\mathrm{K}_{\mathrm{sp}}=27 \mathrm{~s}^4$
4. DThe solubility product and the molar solubility of $\mathrm{Ca}_3$\left(\mathrm{PO}_4\right)_2$are related as$27 \mathrm{~s}^4
