Chemical and physical properties
BICAR® PHARMA 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.
2 NaHCO3 --> CO2 + H2O + Na2CO3
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.
