Sodium bicarbonate Chemical Properties,Uses,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

Commonly used laboratory reagent
