OriginDerived from sodium chloride (salt) or mineral deposits containing natural soda ash (trona ore). Produced through the Solvay process, which involves ammonia, carbon dioxide, and brine solution in a series of chemical reactions.
Sodium Carbonate is the disodium salt of carbonic acid with alkalinizing property. When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide. As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid.
Solubility Freely soluble in water. Insoluble in ethanol
