Sodium bicarbonate Chemical Properties,Usage,Production

Chemical Properties
white powder or crystals
General Description
Odorless white crystalline powder or lumps. Slightly alkaline (bitter) taste. pH (of freshly prepared 0.1 molar aqueous solution): 8.3 at 77°F. pH (of saturated solution): 8-9. Non-toxic.
Air & Water Reactions
Stable in dry air, but slowly decomposes in moist air. Moderately water soluble. Decomposes slowly in water (accelerated by agitation) .
Reactivity Profile
Sodium bicarbonate reacts exothermically with acids to generate non-toxic carbon dioxide gas. Decomposes when heated. Incompatible with acids, acidic salts (dopamine hydrochloride, pentazocine lactate, many alkaloidal salts) aspirin and bismuth salicylate.
Fire Hazard
Literature sources indicate that Sodium bicarbonate is noncombustible.
Biological Activity
