Mg(OH)2(s) <----------------> Mg+2(aq) + 2OH-(aq)
Ksp = [Mg+2][OH-]2
Ksp = 1.20 x 10-11
[Mg+2] = S mol /L
[OH-] = 2S mol /L
1.20 x 10-11 = [S] [2S]2
1.20 x1 0-11 = 4S3
S3 = 3.0 x 10-12
S = 6.70 x 10-5 mol/L
[Mg+2] = S = 6.70 x 10-5 mol/L
[OH-] = 2S = 2 x 6.70 x 10-5 = 1.34 x 10-4 mol/L

a Saturated solution of magnesium hydroxide is prepared and the excess solid magnesium hydroxide is allowed to settle. A 25ml aliquot of the saturated solution is withdrawn and transferred to an Erlenmeyer flask, and two drops of methyl orange indicator are added. A 0.00053 M HCl solution(titrant) is dispensed from a buret into the solution (analyte). The solution turns from yellow to a very faint red-orange after the addition of 13.2ml a.
