Baking soda is a chemical compound that is formed by combining sodium, hydrogen, carbon and oxygen. These elements undergo a chemical reaction to form baking soda. The chemical formula for baking soda is NaHCO3, and its chemical name is sodium hydrogen carbonate.
Baking soda is a weak base in terms of acidity, and it is commonly used as an antacid because it can neutralize the acidic juices in the stomach. Acidic and basic spills can both be cleaned up using baking soda. Baking soda is amphoteric, which means that it can react with bases and acids. In cooking, baking soda reacts with acidic ingredients to act as a leavening agent.
