In pairs; Let’s say you add 10.0 g PbCl2 (s) to 1.0 L of water. Even though PbCl2 is ‘insoluble’, a fraction of the solid will dissolve. Write out the chemical equilibrium for the dissolution of PbCl2 in water. The Ksp for PbCl2 is 1.7 x 10-4. Calculate how many grams of PbCl2 will dissolve in the solution. Your lab partner claims that by adding NaCl to the solution, thus increasing [Cl-] and forcing the equilibrium back toward PbCl2 (s),...
