Final answer:

Magnesium hydroxide is used to balance the pH of the human stomach by neutralizing excess stomach acid with hydrochloric acid through a chemical reaction.


Explanation:

Magnesium hydroxide [Mg(OH)2] is used to balance the pH of the human stomach. When Mg(OH)2 reacts with hydrochloric acid (HCl) in the stomach, it forms magnesium chloride and water:

Mg(OH)2 + 2HCl → MgCl2 + 2H2O

This reaction helps neutralize the excess stomach acid, providing relief from issues like indigestion or heartburn.
