Sodium bicarbonate is also known as sodium hydrogen carbonate and is commonly named baking soda. It is a white crystalline powder and insoluble in ethanol but slightly soluble in acetone. It is highly water-soluble, and the solubility increase with rising temperature. Evaporation separates it from water.  Sodium bicarbonate has a bitter odor and salty taste; sometimes, it forms lumps. It is an inorganic and amphoteric compound (it acts as both acid and base). Deposits of sodium bicarbonate are found naturally all over the globe, which is called nahcolite.

Sodium bicarbonate is present in large deposits, but industries also prepare it. The most popular method for synthesizing sodium bicarbonate is the Solvay process; in this process, sodium chloride reacts with ammonia and carbon dioxide and decomposes into sodium carbonate. The product then treats with carbon dioxide and water to obtain sodium bicarbonate. Sodium bicarbonate is a non-toxic compound, but it is an amphoteric compound that means it acts as a base as well as an acid. Therefore, sodium bicarbonate can cause damage to the eyes. Its effects can be fatal when it reacts with the acid, as it releases fumes of carbon dioxide that can cause suffocation.

Sodium bicarbonate is known as baking soda and has a wide range of uses in the food industry. It is used in food as a leavening agent and also as a raising agent for bread cakes. Sodium bicarbonate also has application in medical and pharmaceuticals; it is used as an antacid to treat acidity and heart bun by neutralizing stomach acid. Personal hygiene products like toothpaste and detergents use sodium bicarbonate as a buffering agent.
