Silver chromate is sparingly soluble in aqueous solutions. The Ksp of Ag2CrO4 is 1.12× 10–12. What is the solubility (in mol/L) of silver chromate in 1.4 M potassium chromate aqueous solution? In 1.4 M silver nitrate aqueous solution? In pure water?

  2. .......Ag2CrO4 ==> 2Ag^+ + CrO4^2-
    I.......solid.......0........0
    C.......solid.......2x.......x
    E.......solid.......2x.......x

    For pure water. Substitute E line into Ksp expression and solve for x. That is the solubility of Ag2CrO4 in mol/L.

    In 1.4M AgNO3.
    Substitute E line into Ksp expression EXCEPT (Ag^+) is not x but 1.4+2x. Solve for x and that is solubility Ag2CrO4 in mols/L.

    For K2CrO4 solution.
    Substitute E line into Ksp expression EXCEPT (CrO4^2-) is not x + 1.4+x. Solve for x which is solubility Ag2CrO4 in mols/L.
