How is baking soda made?



  1. 0 Votes

    Baking soda (a.k.a. sodium bicarbonate) is made in modern times either from a method called Solvey (the chemist who discovered it) or from a mineral called Trona ore. In the Solvey method, carbon dioxide, ammonia, and sodium chloride are mixed until sodium bicarbonate forms as a precipitate (the solid that is left). It is then heated and purified to be used as food grade baking soda. But deriving (refining) baking soda from Trona ore is a less polluting process, thus gaining in popularity.
