Which type of salt is found in antacid medications and is used to relieve heartburn and indigestion?

Explanation

Magnesium salts like magnesium chloride are common ingredients in antacid tablets. These compounds neutralize excess stomach acid that causes heartburn and discomfort.

When magnesium chloride dissolves in stomach acid, it reacts to form water and other harmless substances. This reaction reduces the acidity in your stomach, providing relief from burning sensations.

Other magnesium compounds like magnesium hydroxide are also used in antacids. Silicon, boron, and sulfur chlorides are toxic chemicals not suitable for human consumption.
