Sodium bicarbonate or sodium hydrogen carbonate is the chemical compound with the formula NaHCO3
Properties: white crystalline powder. No olfactory and taste salty. 2.159g/cm3 density. Water-soluble, alkaline aqueous solution was not soluble in ethanol. In the dry air of stability, moist air can slow decomposition. Heat to 270 ° C and above all hydrolysis and emit carbon dioxide as sodium carbonate.
Application:of a food industry's most widely used sulfur relaxants, for the production of biscuits, cakes, buns, bread, soda is the beverage of carbon dioxide occurred agent; With alum as composite alkaline inspired, but also with civil Soda composite stone base; butter also can be used as a preservation agent. Fire equipment are used in the production of foam and the acid-base Extinguisher Extinguisher. Rubber industry with the use of alum, H agent with the hole with a hole uniform for the role of rubber, sponge production. Metallurgical industry for ingot casting a flux. Industrial machinery for steel (refined) Sand Molding agents. Dyeing Printing Industry for staining the fixing agent, pH buffers, fabric dyeing and post-processing agent. The pharmaceutical industry used acid on raw materials.
