一般描述

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

应用

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]
