Question

1. Fill in the following table with the Ksp values for any insoluble salt that forms from a metal ion in the left column and the anions in the other columns. Some are already done for you. If a salt is soluble in water write N/A (0.5pt). Prelab Table. Selected Ksp Values Metal Cl- OH- SO4 2- CrO4 2- C2O4 2- Ag+ 1.8 x 10-10 Pb2+ 1.7 x 10-5 1.4x10-20 Hg2 2+ 1.4 x 10-18 Ba2+ Ca2+ Mg2+ Na+ K+ NH4+ a) Why were you unable to find some of the Ksp values for some ions (0.5pt)? Type your response here. 2. In a test tube containing a precipitate of PbCrO4 in water: What are the concentrations of the lead (II) and chromate ions in equilibrium with the solid? Show your calculations. Use the Ksp from the Prelab table above (0.5pt). Type your response here. [Pb+2] = M [CrO4-2] = M
