Formula Mg(OH)2 is a white solid with low solubility in water (K sp = 5). Magnesium hydroxide, a common component of antacids, such as magnesia milk, is 610-12. It occurs in nature as the mineral brucite. It can be economically extracted directly from seawater by treating sea water with lime. A tonne of Mg (or 160,000 US gallons) of seawater gives about one ton of mg. (OH) 2. It is made on a commercial scale by treating sea water with lime (Ca(OH), which is much more soluble.
Is Magnesium Hydroxide A Base – Answer & Related Questions
All magnesium hydroxide that does dissociate will dissociate into ions. Magne hydroxide is a strong electrolyte, since the dissociation of this small amount of dissolved magnesium hydroxide is complete. Its low solubility makes it a poor base.
