    If
    the solubility product of CuS is 6 × 10-16,
    calculate the maximum molarity of CuS in aqueous solution.
    Ans : Solubility product of
    CuS, Ksp = 6 × 10-16
    Let s be the
    solubility of CuS in mol L-1.

    Now,
    = s × s
    = s2
    Then, we have, Ksp =

    = 2.45 × 10-8 mol L-1
    Hence, the maximum
    molarity of CuS in an aqueous solution is 2.45 × 10-8 mol L-1.
