Magnesium hydroxide is the inorganic compound with the chemical formula $\mathit{M}\mathit{g}{\left(\mathit{O}\mathit{H}\right)}_2$. It occurs in nature as the mineral brucite. It is a white solid with low solubility in water $\left({\mathit{K}}_{\mathit{s}\mathit{p}}=5.61\times {10}^{-12}\right)$. Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives.
