Magnesium Hydroxide and Hydrochloric Acid (Milk of Magnesia)

Mg(OH)2 + 2HCl → MgCl2 + 2H2O

Обзор

Magnesium hydroxide (milk of magnesia) neutralizes hydrochloric acid to form magnesium chloride and water. As a sparingly soluble base, magnesium hydroxide provides sustained acid neutralization without causing rebound acidity. It works gradually as the solid slowly dissolves and reacts.
