Magnesium Hydroxide MDH Inorganic Additive CAS 1309-42-8 White
Magnesium hydroxide is a new type of filling flame retardant with
the chemical formula Mg(OH)2.
It is often known as milk of magnesia, because of its milk-like
appearance as a suspension. While magnesium hydroxide has a low
solubility in water, with a Ksp of 1.5×10−11, it is large enough
that it will partially dissolve to produce ions in the solution,
forming the suspension.
A relatively high concentration of magnesium or hydroxide ions
would be required to revert the suspension to the solid precipitate
by reversing the equilibrium.
In this suspended form, magnesium hydroxide is a common component
of antacids and laxatives; it interferes with the absorption of
folic acid and iron.
The antacid properties come from the hydroxide ions which are
responsible for neutralising the acid.
The solid mineral form of magnesium hydroxide is known as brucite.
