Physical properties of sodium bicarbonate:
For white crystal, or opaque monoclinic crystal system fine crystal.
Odorless, non-toxic, salty, soluble in water, slightly soluble in ethanol.
Soluble in 10 parts water at 25℃, soluble in 12 parts water at about 18℃.
Its aqueous solution was slightly alkaline due to hydrolysis, stable in normal temperature, easy to decompose under heat, gradually decomposed above 50℃, completely lost carbon dioxide at 270℃, no change in dry air, slow deliquesce in the humid air.
In medical use, sodium bicarbonate combined with streptomycin can enhance the antibacterial effect of the urinary tract. Gynecology for fungal vaginitis, with 2% ~ 4% solution sitz bath, every night, each time 500 ~ 1000 ml, continuous use for 7 days.
precautions for use: Sodium bicarbonate is a very weak alkali which is close to neutral at room temperature. If its solid or aqueous solution is heated above 50℃, it can be converted into sodium carbonate, which is irritating and corrosive to people and irritating to eyes, skin, and respiratory tract mucosa, causing inflammation. Therefore, a high temperature above 50℃ should be avoided when it be using.
