Antacid tablets, commonly used to relieve heartburn and indigestion, work by doing what to excess stomach acid?

Explanation

Antacid tablets typically contain a mild base, such as calcium carbonate or magnesium hydroxide, which works by neutralizing some of the excess hydrochloric acid naturally present in the stomach, helping relieve the discomfort associated with heartburn or indigestion. This neutralization is a straightforward acid-base reaction, in which the base reacts with excess acid to form a neutral salt and water, reducing the overall acidity in the stomach. While generally safe for occasional use, relying on antacids very frequently is usually a signal to consult a doctor about a possibly underlying digestive issue.
