Magnesium Hydroxide and Hydrochloric Acid (Antacid)

Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O

Tổng quan

Magnesium hydroxide (milk of magnesia) neutralizes hydrochloric acid to form magnesium chloride and water. This is exactly the reaction that occurs in the stomach when antacid tablets are taken. Magnesium hydroxide is a mild base that neutralizes acid without causing rebound acidity.
