The solubility product constant for Mg(OH)2\text{Mg(OH)}_2 is Ksp=5.6×10−12K_{sp}=5.6\times10^{-12}. What is the approximate molar solubility of Mg(OH)2\text{Mg(OH)}_2 in a solution buffered at pH 12? (a) 5.6×10−6 M5.6\times10^{-6}\,\text{M} (b) 1.1×10−4 M1.1\times10^{-4}\,\text{M} (c) 5.6×10−8 M5.6\times10^{-8}\,\text{M} (d) 5.6×10−10 M5.6\times10^{-10}\,\text{M}
