1,physical property
White crystal powder,non-toxic,salty in taste,soluble in water and aqueous solution,insoluble in ethanol, alkalescence,deliquescent in the air,easily labile at high temperature,release carbon dioxide.
2,Chemical property
(1)NaHCO3+HCL=NaCL+H2O+CO2
(2)NaHCO3+H2O<-->NaOH+H2CO3
(3)Easily labile at high temperature:sodium bicarbonate is easily resolved into sodiym carbonate and carbon dioxide.
3,Primarily use in food fermentation,pharmacy,tanning,mineral separalion,smelt,extinguishant,feed additive,Spirulina breeding,daily chemical,rubber,dyestuff,oil,environmental production and so on.
In food processing, sodium bicarbonate is the most widely used bulking agent, which is used to produce biscuits, bread, etc., but sodium carbonate will remain after the action. Too much use will make the food too alkaline and cause the flavor to deteriorate.
