When 100 mL each of 2.0 × 10-4 M Ca2+ and 2.0 × 10-2 M F- aremixed, what is the remaining Ca2+ ion concentration ? Thesolubility product constant of CaF2 is 5.3 × 10-9. (Hint: Determinethe limiting reactant, the concentration of excess reactant afterprecipitation, and how the concentration of excess reactantinfluences the solubility of CaF2).
