The chemical name of baking soda is sodium bicarbonate (NaHCO 3) or sodium hydrogen carbonate. Sodium hydrogen carbonate is produced on a large scale by reacting a cold and concentrated solution of sodium chloride (called brine) with ammonia and carbon dioxide.

Sodium carbonate is a white crystalline solid which exists as a decahydrate (Na 2 CO 3 .10H 2 O). This is called washing soda. When decahydrate gets heat, it looses the water of crystallization to form monohydrate ( Na 2 CO 3 .H 2 O). Above 373K, the monohydrate becomes completely anhydrous and changes to a white powder called soda ash.
Sodium carbonate (Na2CO3) also known as washing soda or soda ash is a sodium salt of carbonic acid. It is generally prepared by ammonia soda or Solvey process. A common source of sodium carbonate is the ashes of plants sometimes called soda …
(b) Dilute hydrochloric acid was titrated with sodium carbonate solution. • 10.0 cm3 of 0.100 mol / dm3 hydrochloric acid were placed in a conical flask. • A few drops of methyl orange indicator were added to the dilute hydrochloric acid. • The mixture was titrated with sodium carbonate so lution.
produce sodium bicarbonate is worth more than the sodium bicarbonate. Were it not for the recycling of ammonia, the Solvay process would be economically impractical. Sodium hydrogen carbonate is used in medicine (frequently as an antacid), as a leavening agent in baking (it is "baking soda"), and in the manufacture of sodium carbonate, Na2CO3.
