How Is Baking Soda Made?
The common name for baking soda is sodium bicarbonate, a chemical ingredient that was found around 4 million years ago when the salt lakes were evaporated and formed deposits of trona. The trona rocks further processed into soda ash, i.e., sodium bicarbonate. Wyoming has the world’s largest trona deposit. Seventeen million trona are produced every year.
The combination of acid, carbonic forms baking soda or sodium bicarbonate, and a base, sodium hydroxide that reacts with other chemicals working as a mild alkali. Baking soda decomposes into sodium carbonate, carbon dioxide, and water.
The natural chemical and physical properties of baking soda make it ideal for a wide range of applications in cleaning, buffering, deodorizing, and fire extinguishing, as well.
