Uses
sodium bicarbonate (baking soda) is an inorganic salt used as a buffering agent and a pH adjuster, it also serves as a neutralizer. It is used in skin-smoothing powders.
Uses
Sodium Bicarbonate is a leavening agent with a ph of approxi- mately 8.5 in a 1% solution at 25°c. it functions with food grade phosphates (acidic leavening compounds) to release carbon dioxide which expands during the baking process to provide the baked good with increased volume and tender eating qualities. it is also used in dry-mix beverages to obtain carbonation, which results when water is added to the mix containing the sodium bicarbonate and an acid. it is a component of baking powder. it is also termed baking soda, bicarbonate of soda, sodium acid carbonate, and sodium hydrogen carbonate.

Hazard Information

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.
Reactivity Profile
SODIUM BICARBONATE(144-55-8) 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.
Air & Water Reactions
Stable in dry air, but slowly decomposes in moist air. Moderately water soluble. Decomposes slowly in water (accelerated by agitation) .
Fire Hazard
Literature sources indicate that this chemical is noncombustible.
