General description
Sodium hydrogencarbonate commonly known as sodium bicarbonate is a white crystalline solid or powder. A study of the crystalline structure shows that the bicarbonate ion has C2v symmetry. Ruthenium catalyzed hydrogenation of sodium bicarbonate to form sodium formate has been reported.[1]
Application
Sodium hydrogencarbonate (sodium bicarbonate) may be used in the following processes:
- As an alkalizing agent for treating metabolic acidosis.
- For buffering local anesthetics (LA).
- To facilitate the oxidation of styrene and cyclohexene.
- As a medium to fabricate graphene hydrogel.
