Overview
Sodium bicarbonate reduces stomach acid. It is used as an antacid to treat heartburn, indigestion, and upset stomach. Sodium bicarbonate is a very quick-acting antacid. It is a white solid that often appears as a fine powder. It is an amphoteric compound and is used in a wide host of manners.
