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),...
A student measures the molar solubility of barium phosphate in a water solution to be 6.62×10-7 M. Based on her data, the solubility product constant for this compound is B.The solubility of PbCl2 is measured and found to be 4.62 g/L. Use this information to calculate a Ksp value for lead chloride. Ksp = C. The solubility of Ag3PO4 is measured and found to be 1.99×10-3 g/L. Use this information to calculate a Ksp value for silver phosphate. Ksp =
