Question:
A solution containing {eq}Pb^{2+} {/eq} and a solution containing {eq}IO_3^- {/eq} are poured together and quickly mixed. After mixing, the solution contains 0.0030 M {eq}Pb^{2+} {/eq} and 0.040 M {eq}IO_3^- {/eq}. Immediately {eq}Pb(IO_3)_2 {/eq}(s), which has Ksp={eq}2.5 \times 10^{-13} {/eq}, begins to precipitate. Calculate the free concentrations of {eq}Pb^{2+} {/eq} and {eq}IO_3^- {/eq} after the precipitation reaction comes to equilibrium.
Calculation of Ions from the Dissolution of Sparingly Soluble Salt at Equilibrium
Insoluble salts form an equilibrium condition in an aqueous medium. The equilibrium reaction liberates some ions that can be quantified using the solubility constant of the salt.
