How Mg(OH)2 reduce the amount of acid in the stomach?

Magnesium hydroxide (Mg(OH)2) reacts with stomach acid (hydrochloric acid, HCl) to form magnesium chloride and water. This reaction helps neutralize excess acid in the stomach, providing relief from conditions like heartburn and indigestion. Magnesium hydroxide acts as an antacid by raising the pH in the stomach and reducing acidity.
