Can you please solve this
Sodium hydroxide is added to a solution containing Mg2+ to produce a pH of 11.0 and form a precipitate of Mg(OH)2. (a) Given the Ksp of Mg(OH)2(s) is 6.0 x 10", calculate the molar concentration of Mg?* in solution. (b) The K, for Ca(OH),(s) is 6.5 x 10º. Explain how pH adjustment can be used to distinguish the presence of Mg from Ca“ in an EDTA titration of "hard" water containing both cations.
