Best ResponseYou've already chosen the best response.1The KSP depends on the concentration of the ions that are in solution, specifically, their products\[K{_S}{_P} = [M+][NM]\] where M and NM are the metal and nonmetal ions that make up the solution. Since each formula has a 1:1 ratio of its ions, their concentrations will be equal. The KSP gives a way to find the maximum allowable concentrations of the ions that will be present in solution before a precipitate forms. Since PbS has the smallest KSP, it's concentrations will be the smallest:\[K{_S}{_P} = [Pb{^+}{^2}]*[S{^}{^2}] = 1.10x10{^}{^2}{^0}\]The other salts will have larger concentrations of ions present before precipitation occurs
