Solid silver chromate is added to pure water at 25 C. Some of the solid remains undissolved at the bottom of the flask. The mixture is stirred for several days to ensure that equilibrium is achieved between the undissolved Ag2CrO4 and the solution. Analysis of the equilibrated solution shows that its silver ion concentration is 13*10^-4 M. Assuming that Ag2CrO4 dissociates completely in water and that there are no other important equilibria involving Ag+ or CrO4^2- ions in the solution, calculate ksp for this compound. Then express the solubility of Ag2CrO4 in mol/L as well as g/L.
