Answer the following questions concerning magnesium hydroxide, Mg(OH)2. (a) A saturated solution of Mg(OH)2(s) is prepared that is in equilibrium with Mg(OH)2(s). Write the solubility-product expression, Ksp, for Mg(OH)2. (b) The pH of a saturated solution of magnesium hydroxide is equal to 10.52. (i) Calculate the value of [OH-] in this saturated solution: (ii) Calculate the value of [Mg2+] in this solution: (c) Calculate the value of Ksp for Mg(OH)2 (d) In a different experiment, 50.0 mL of 4.0 x 10-4 M Mg(NO3)2 was added to 50.0 mL of 3.0 x 10-4 M NaOH. Assume that the final volume of this solution is 100.0 ml. Will a precipitate form in this experiment? Justify your answer by using calculations.
