The \(\mathrm{K}_{\mathrm{sp}}\) for the following dissociation is \(1.6 \times 10^{-5}\) \(\mathrm{PbCl}_{2(\mathrm{s})} \rightleftharpoons \mathrm{Pb}_{(\mathrm{ag})}^{2+}+2 \mathrm{Cl}_{(\mathrm{aq})}^{-}\) Which of the following choices is correct for a mixture of \(300\; \mathrm{mL}\;\; 0.134 \;\mathrm{M} \;\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}\) and \(100\; \mathrm{mL}\;\; 0.4\; \mathrm{M}\; \mathrm{NaCl} ?\)
- A \(\mathrm{Q} < \mathrm{K}_{\mathrm{sp}}\)
- B \(\mathrm{Q} > \mathrm{K}_{\mathrm{sp}}\)
- C \(\mathrm{Q} = \mathrm{K}_{\mathrm{sp}}\)
- D Not enough data provided
Answer & Solution
Correct Answer
(B) \(\mathrm{Q} > \mathrm{K}_{\mathrm{sp}}\)
Step-by-step Solution
Detailed explanation
\(\left[\mathrm{Pb}^{2+}\right] =\frac{300 \times 0.134}{400}\) \(=1.005 \times 10^{-1} \mathrm{M}\) \(\left[\mathrm{C}^{-}\right] =\frac{100 \times 0.4}{400}\) \(=10^{-1} \mathrm{M}\)…
