一般說明

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.

應用

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.
