Practice ProblemATTEMPT

Lead(II) nitrate is added slowly to a solution that is $\text{0}\text{.020 }M{\text{ in Cl}}^{\text{-}}$ ions. Calculate the concentration of ${\text{Pb}}^{\text{2+}}$ ions (in mol/L) required to initiate the precipitation of ${\text{PbCl}}_{\text{2}}\text{.}\left(K_{\text{sp}}{\text{ for pbCl}}_{\text{2}}\text{ is 2}\text{.4}\times {\text{10}}^{\text{-4}}.\right)$
