Sodium Bicarbonate
Time£ļ2018-8-3 16:51:15°°Page view£ļ824

Sodium bicarbonate, chemical formula NaHCO₃, commonly known as baking soda. White fine crystals,

less soluble in water than sodium carbonate. It is also an industrial chemical.

 Solids begin to decompose gradually at temperatures above 50 °„ C, producing sodium carbonate,

carbon dioxide and water, which completely decomposes at 270 °„ C.
Chinese name Sodium Bicarbonate English name Sodium Bicarbonate
Alternative Names Baking Soda, Sodium Bicarbonate, Sodium Carbonate, Heavy Cao, Baking Soda

Appearance of white powder or monoclinic crystalline powder is commonly known as baking soda,

 which can be used for cooking pasta
The sodium carbonate solution is carbonized by carbon dioxide in sodium carbonate,

and then separated and dried to obtain a finished product.

Sodium bicarbonate can be directly used as a raw material for the pharmaceutical industry to treat hyperacidity.

It can also be used in filmmaking, tanning, beneficiation, smelting, metal heat treatment, as well as in the fiber and rubber industries.

 It is also used as a detergent for wool and for soaking in agriculture. One of the most widely used loosening agents in the food industry.

 It is used in the production of biscuits, cakes, steamed bread, bread, etc. It is a carbon dioxide generator in soda drinks;

 it can be combined with alum as alkaline baking powder, or with soda ash for civilian use Carnitine;

can also be used as a butter preservative.
Fire equipment is used to produce acid and alkali fire extinguishers and foam fire extinguishers.

The rubber industry uses it in combination with alum and sodium bicarbonate pore-forming agents to play the role of uniform pores for rubber and sponge production. The metallurgical industry is used as a flux for casting steel ingots. The machinery industry is used as a molding aid for casting steel (sand foundry) sand molds. The printing and dyeing industry is used as a fixing agent for dyeing and printing, a buffer agent for acid and alkali, and a post-treatment agent for fabric dyeing and finishing. Adding baking soda to the dyeing can prevent the yarn cone from generating color flowers. The pharmaceutical industry is used as a raw material for antacids.
Used as analytical reagent, inorganic synthesis, pharmaceutical industry, fermenting agent for treating acidemia and food industry, carbon dioxide generator in soft drinks and cold drinks, and butter preservative. It can be directly used as raw materials in the pharmaceutical industry, as detergent for wool, foam fire extinguishing agent, bath agent, alkaline agent and leavening agent. It is often used with ammonium bicarbonate to prepare leavening agents for biscuits and cakes. 20g / kg is added to wheat flour. It can be used with citric acid, tartaric acid and other foaming agents to produce solid refreshing beverages (producing CO₂).
Sodium bicarbonate is white crystal or fine crystal of opaque monoclinic system. The specific gravity is 2.15. Odorless, non-toxic, salty, soluble in water, slightly soluble in ethanol. It is soluble in 10 parts of water at 25 °„ C and 12 parts of water at about 18 °„ C. Its aqueous solution is slightly alkaline due to hydrolysis. It is stable at room temperature and easily decomposes when heated. It gradually decomposes above 50 °„ C, completely loses carbon dioxide at 270 °„ C, has no change in dry air, and slowly deliquesces in humid air.
It is a white crystalline powder; odorless and salty; it decomposes slowly in humid air, and the aqueous solution is left for a long time, or shaken, or heated, and the alkalinity is increased. Soluble in water and insoluble in ethanol.
Packaging specifications 25kg ton bag
