A solution contains 0.036 M Ag+ and 0.031 M Pb²+. If you add Cl¯, AgCl and PbCl₂ will begin to precipitate. What is the concentration of Cl required, in molarity, when AgCl precipitation begins? concentration of Cl- = What is the concentration of Cl required, in molarity when AgCl precipitation is 99.99% complete? concentration of Cl- = What is the concentration of Cl required, in molarity when PbCl₂ precipitation begins? concentration of Cl- = What is the concentration of Cl required, in molarity when PbCl₂ precipitation is 99.99% complete? concentration of Cl- = Finally, give the Cl- concentration range in which Ag+ can be completely separated from Pb²+ by precipitation. Give the lowest CI concentration for the separation of Ag+ from Pb²+. concentration of Cl- = Give the highest Cl¯ concentration for the separation of Ag+ from Pb²+. concentration of Cl- = M M M M M M
