    Please help with attached problem.

    1. The following data on the solubility of Mg(OH)2 has been measured in buffers with different pH values. Using linear regression estimate the solubility product (Ksp) for Mg(OH)2 .

    Solubility (S) of Mg(OH)2 pH

    0.151 M 9.8
    2.39*10-3 M 10.7
    2.73*10-4 M 11.2
    9.5*10-6 M 11.9
    S=? 7.00

    Do the regression between pH and S.
    Then find the value of S for pH at 7.00
    And Ksp=4S3.
