Calculate the solubility of calcium sulfate in grams solute per 100 grams of solvent. Assume that the volume occupied by the solute in the solution is negligibly small. (Ksp for CaSO4 = 2.4 X 10^-5)

  • Chemistry - ,

    CaSO4>> Ca++ + SO4--

    Ksp= x^2
    2.4E-5=x^2
    x= 4.89E-3 moles/liter
    in grams per liter, 4.89E-3*(136)/10 = .067grams/100gH2O
