Sodium bicarbonate (NaHCO3) (baking soda) is a substance found in all living things, regulating pH balance. Made from sodium carbonate (soda ash), soda ash is mined from trona ore. The soda ash is dissolved in a solution containing carbon dioxide. Sodium bicarbonate precipitates out naturally. Sodium bicarbonate is utilized in a multitude of applications, not the least of which is the soda-acid fire extinguisher.
