To calculate the solubility product, Ksp, of the compound Ag2CrO4. We need its dissociation reaction and the concentration of each ion in the solution. Since the concentration is not given then we can only show an expression for the calculation of such.
Ag2CrO4 > 2Ag+ + CrO4-2
Ksp = [Ag+]² [CrO4 2-]
