Descripción

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 C_2v symmetry.[1] Ruthenium catalyzed hydrogenation of sodium bicarbonate to form sodium formate has been reported.[2]

Application

Sodium hydrogencarbonate (sodium bicarbonate) may be used in the following processes:

• As an alkalizing agent for treating metabolic acidosis.[3]
• For buffering local anesthetics (LA).[3]
• To facilitate the oxidation of styrene and cyclohexene.[4]
• As a medium to fabricate graphene hydrogel.[5]
