b A useful commercial source of magnesium is sea water where Mg aq is 0 054 mol dm 3 The magnesium is precipitated from solution by adding calcium hydroxide Mg2 aq Ca OH s Ca aq Mg OH s i Write an expression for the Ksp of Mg OH 2 including its units ii The numerical value for Kp is 2 00 x 10 11 Calculate Mg aq in a saturated solution of Mg OH 2 iii Hence calculate the maximum percentage of the original magnesium in the seawater that this method can extract
