A solution is 0.1M in Cl - and 0.1M in CrO 4 -- ions. If solid AgNO 3 is gradually added to this solution which one will precipitate first? At what concentration of Cl - , Ag 2 CrO 4 starts precipitating? (K sp of AgCl= 1.7x10 -19 , K sp of Ag 2 CrO 4 = 1.9x10 -12 ).

Dear student,

  • Solubility Product, Ksp, refers to an ionic compound dissolving to form ions
  • For the reaction: MA(s) M+(aq) + A-(aq)

    The equilibrium constant K is:

    K = [M+][A-]



  • Since the concentration of the solid is a constant, it is effectively incorporated into the equilibrium constant: Ksp = [M+][A-]
  • [M+][A-] is referred to as the ion product.
  • At equilibrium, the ion product = solubility product (Ksp) and the solution is said to be saturated.
  • A precipitate will form when two solutions are mixed if the ion product is greater than the solubility product, ie, [M+][A-] > Ksp
