Chemistry - Ionic Equilibrium Question with Solution | TestHub

The${\mathrm{K}}_{\mathrm{s}\mathrm{p}}$for the following dissociation is$1.6\times {10}^{-5}$
${\mathrm{P}\mathrm{b}\mathrm{C}\mathrm{l}}_{2\left(\mathrm{s}\right)}\rightleftharpoons \mathrm{P}{\mathrm{b}}_{\left(\mathrm{a}\mathrm{q}\right)}^{2+}+2\mathrm{C}{\mathrm{l}}_{\left(\mathrm{a}\mathrm{q}\right)}^{-}$
Which of the following choices is correct for a mixture of$300 \mathrm{m}\mathrm{L }\mathrm{0.134 }\mathrm{M} \mathrm{P}\mathrm{b}{\left(\mathrm{N}{\mathrm{O}}_3\right)}_2$and$100 \mathrm{m}\mathrm{L}$$\mathrm{0.4 }\mathrm{M }\mathrm{}\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}?$
