Question

We are trying to precipitate lead (II) bromide ($K_{sp} = 6.6 \times 10^{-6}$). We do so by mixing a saturated 1.000 L solution of $Pb^{2+}$ ions with 0.100 mol of solid KBr, which dissolved completely. What is the equilibrium concentration of $Pb^{2+}$ in this solution?

Step 1

Since PbBr2 is insoluble, it will precipitate out of the solution. The equilibrium concentration of Pb2+ ions will be determined by the solubility product constant (Ksp) of PbBr2. Show more…
