Chemical names

Sodium hydrogen carbonate
Sodium bicarbonate
Natrii hydrogenocarbonas
Carbonic acid mono sodium salt
Baking soda

Presentation

Sodium bicarbonate consists of white crystals or of white, granular or crystalline powder. It is soluble in water and decomposes during heating in the dry state or in solution to sodium carbonate under evolution of CO₂ gas. CO₂ gas is also formed during reaction with acids:

NaHCO₃ + HCl    -->  NaCl + CO₂ + H₂O

NaHCO₃ + CH₃CHOHCOOH  -->  CH₃CHOHCOONa + CO₂ + H₂O

The pH value of Sodium Hydrogen Carbonate in an aqueous 1 % solution is about 8,4.

Applications*

Sodium Hydrogencarbonate is widely used in pharmaceutical formulations, as source of carbon dioxid in effervescent tablets, for pH adjustment, as buffering agent, as antacid or in dialysis solutions.
Depending on those different applications in ethic medicines or OTC products Sodium Hydrogencarbonate can be defined as active pharmaceutical ingredient (API), as excipient or as component in a medical device.
