Magnesium Hydroxide and Hydrochloric Acid (Milk of Magnesia)

Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O

Visão geral

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.
