A solution contains $1.0 \times 10^{-3}$ mol L$^{-1}$ Ba$^{2+}$ and $1.0 \times 10^{-3}$ mol L$^{-1}$ Ca$^{2+}$. NaF is then dissolved to give an initial concentration of $1.0 \times 10^{-2}$ mol L$^{-1}$. Does a precipitate form? If so, is it BaF$_2$, CaF$_2$ or both? $K_{sp}$ of BaF$_2 = 1.5 \times 10^{-6}$; $K_{sp}$ of CaF$_2 = 3.2 \times 10^{-11}$ Only CaF$_2$ precipitates Only BaF$_2$ precipitates both BaF$_2$ and CaF$_2$ precipitate no precipitate forms
