A) A saturated solution of lead(II) fluoride, PbF2 , was prepared by dissolving solid PbF2 in water. The concentration of Pb2+ ion in the solution was found to be 2.08 x 10-3 M . Calculate Ksp for PbF2 .
B) The value of Ksp for silver sulfide, Ag2S , is 8.0x10^-51 . Calculate the solubility of Ag2S in grams per liter. If you could, can you tell me how u did them?
