Sodium bicarbonate (baking soda): CAS: 144-55-8 Molecular Formula: NaHCO3 Molecular Weight: 84.01 Chinese name: sodium bicarbonate, sodium bicarbonate baking soda is different from the industrial base of soda ash (sodium carbonate) and baking soda ( sodium bicarbonate), baking soda is the absorption of carbon dioxide by the soda ash solution or crystalline manufactured goods, both essentially no difference. Therefore, baking soda in some places also called the the edible alkali (powder). Baking soda solid, round, white color, soluble in water properties [Edit this paragraph] white powder or opaque fine crystalline monoclinic system. Specific gravity 2.159. Odorless, salty taste, soluble in water, slightly soluble in ethanol. The aqueous solution was slightly alkaline hydrolysis, the heat decomposition easy, rapid decomposition above 65 ° C, complete loss of carbon dioxide at 270 ℃, no change in dry air, slowly decomposes in moist air. Use [Edit this paragraph] the leaven used as a food, soft drinks and cold carbon dioxide generating agent, butter preservative. Be directly used as the raw material of the pharmaceutical industry for the treatment of hyperacidity. Can also be used for the filmmakers, tanning, dressing, smelting, metal heat treatment, as well as for fiber, rubber industry. At the same time used as a detergent for wool, foam extinguishing agent, as well as for agriculture soaking. Food industry one of the most widely used bulking agent for the production of biscuits, cakes, bread, bread, soft drinks carbon dioxide generating agent; alum composite alkaline baking powder, soda ash composite for civil The stone base; butter can also be used as a preservative. Fire equipment, fire extinguishers and foam fire extinguisher used in the production of acid-base. Rubber industry in conjunction with alum, H foaming agent and a uniform fat hole role for the rubber, sponge production. Metallurgical industry for ingot casting flux. Mechanical industry as steel casting (foundry) sand forming additives. Printing and dyeing industry as dyeing and printing fixing agent, pH buffer, fabric dyeing and finishing post-processing agent. Raw material for the pharmaceutical industry as antacids.
