Sodium bicarbonate is a white crystal or an opaque mono clinic fine crystal.The proportion is 2.15. Odorless, non-toxic, salty, soluble in water, slightly soluble in ethanol. It is soluble in 10 parts of water at 25 ° C and 12 parts of water at about 18 ° C. The aqueous solution is slightly alkaline due to hydrolysis, stable at room temperature, easily decomposed by heat, gradually decomposes above 50 ° C, completely loses carbon dioxide at 270 ° C, does not change in dry air, and slowly deliquesces in humid air.
· Molecular formula: NaHCO3
· Molecular weight: 84.01
· CAS No.:144-55-8
· Character: It is white crystalline powder or granular, odorless and salty. Easily soluble in water. Insoluble in alcohol ,Aqueous solution is alkalinity. Decomposed when heating, decomposed slowly when exposed to moist air.
· Usage: In food industry , it is used as acidity modifier, CO2 Propellant or used in feedstuff, drug ,medicine, film, mineral selection, metallurgy , fiber and rubber, or used as detergent and fire extinguish agent.
· Storage and transportation: It should be stored in a dry and ventilated warehouse ,kept away from heat and moisture. Unloaded with care so as to avoid damage. Further more it must be stored separately from poisonous substances.
