Application

Magnesium hydroxide, commonly recognized as a key component in the 'milk of magnesia,' serves a dual purpose as both an antacid and a laxative. This white, bulky powder, formed through the reaction of sodium hydroxide with a soluble magnesium salt, appears as a milk-like suspension due to its limited solubility in water. As a mild base, it effectively neutralizes excess stomach acid, providing relief from indigestion and heartburn. Additionally, the magnesium ions present enhance water content in the intestines, promoting bowel movements through osmotic effects. This dual action makes magnesium hydroxide an essential remedy for digestive discomfort.
