Sodium bicarbonate, also known as baking soda, is a white crystalline powder or solid with the chemical formula NaHCO3. It is composed of sodium ions and bicarbonate ions. Sodium bicarbonate has a slightly salty, alkaline taste and is commonly used in baking as a leavening agent, in medicine as an antacid to treat acid indigestion and heartburn, and in cleaning products for its mild abrasive and neutralizing properties.
Chemical Properties
Sodium bicarbonate is an amphoteric compound that reacts with acids to produce carbon dioxide gas, water, and a salt. When heated, it decomposes into sodium carbonate, water, and carbon dioxide. It has applications ranging from food preparation to medical uses, including treatment of acidosis and hyperkalemia.
Uses
- Baking : Helps baked goods rise by releasing CO2.
- Medical : Relieves heartburn, indigestion; used in some medical treatments for acidosis or drug overdoses.
- Cleaning : Acts as a mild abrasive and neutralizer for stains, odors, and grease.
- Personal care : Used in toothpaste for stain removal and deodorants for odor control.
Sodium bicarbonate is generally recognized as safe (GRAS) by the FDA for use as a food additive and medicine.
