See more british gas fuel grantWebI thought that Ksp was a constant and therefore if there is some concentration of Cl ions then the concentration of Ag added for it to precipitate must be some number that will multiply by the concentration of Cl to give the Ksp. Hence, the only situation where this would hold is if [Cl] = sqrt(Ksp). The same goes for when AgCrO4 precipitates. ca or cs best
