Sodium bicarbonate, commonly known as "sodium bicarbonate", "soda powder", "heavy Cao", white fine crystals, has a solubility in water of less than sodium carbonate. It is an industrial chemical that may be toxic. It is easily decomposed by heat. Slow decomposition of solids in humid air above 50 ° C began to gradually decompose to form sodium carbonate, carbon dioxide and water, completely decomposed at 270 ° C. All changed to sodium carbonate at 100 °C. It is soluble in 10 parts of water at 25 ° C, soluble in 12 parts of water at about 18 ° C, and insoluble in ethanol. The non-stirred solution made of cold water has only a slightly alkaline reaction to the phenolphthalein test paper, and the base is increased by placing or raising the temperature. The pH of the freshly prepared 0.1 mol/L aqueous solution at 25 ° C was 8.3. . Sodium bicarbonate is an acid salt formed by neutralization of a strong base and a weak acid, and is weakly alkaline when dissolved in water. This feature makes it a leavening agent in the food making process. Sodium bicarbonate will remain sodium carbonate after its action, and too much use will give the finished product a basic taste. 
Commonly used packaging 
Usually shipped in 25KG, 1000KG 
Uses 
1, sodium bicarbonate can be directly used as a raw material for the pharmaceutical industry, for the treatment of hyperacidity. 
2, can also be used in film production, tanned leather, mineral processing, smelting, metal heat treatment, as well as for the fiber, rubber industry. 
3. Used as a detergent for wool, as well as for agricultural soaking. 
4. One of the most widely used bulking agents in the food industry for the production of biscuits, cakes, taro, bread, etc., is a carbon dioxide generating agent in soda drinks; 
5. It can be combined with alum as an alkaline baking powder, or Soda ash is compounded into civilian stone base; 
6. It can also be used as a butter preservative. 
7. Fire-fighting equipment is used to produce acid-base fire extinguishers and foam fire extinguishers. 
8. The rubber industry uses its role in uniform pores with alum and H porogens for rubber and sponge production. 
9. The metallurgical industry is used as a fluxing agent for casting steel ingots. 
10. The machinery industry is used as a forming aid for cast steel (sanding sand) sand type.
11. The printing and dyeing industry is used as a fixing agent for dyeing printing, an acid-base buffering agent, and a finishing agent for fabric dyeing and finishing. The addition of sodium bicarbonate to the dyeing prevents the yarn from being colored. 
12. The pharmaceutical industry is used as a raw material for antacids. 
13. Used as an analytical reagent, an inorganic synthesis, a pharmaceutical industry, a treatment agent for acidemia, a starter for the food industry, a carbon dioxide generator for soft drinks and cold drinks, and a preservative for butter. 
14, can be directly used as raw materials for the pharmaceutical industry, wool detergent, foam fire extinguishing agent, bath agent, alkaline agent, leavening agent. Often used with ammonium bicarbonate to prepare a leavening agent for biscuits and cakes. 
15. A foaming agent (CO2) which can be formulated into a solid refreshing beverage with citric acid or tartaric acid. 
16. When used alone, it is strongly alkaline due to thermal decomposition. It will be yellow when used in bread and destroy vitamins in wheat. It is best to use it with acidic substances such as calcium hydrogen phosphate. 
17, can still be used for food blanching, to smell. Because it can raise the pH value, it can increase the water holding capacity of the protein, promote the softening of the cells of the food tissue, and promote the dissolution of the astringent component. 
It has a deodorizing effect on goat milk (dosage 10~20mg/kg). 
18, as acidity regulator and chemical leavening agent, China's provisions can be used for all kinds of foods that need to add a leavening agent, according to the production needs of the right amount. 
8. Practical sodium bicarbonate (Remarks) is 
different from soda ash (sodium carbonate) and sodium bicarbonate (sodium bicarbonate) for industrial alkali. Sodium bicarbonate is prepared by absorbing carbon dioxide from a solution or crystal of soda ash. Therefore, sodium bicarbonate is also called edible alkali (powdered) in some places. Sodium bicarbonate is solid, round, white and soluble in water. 
The single salt is divided into: normal salt, acid salt and basic salt. The sodium hydrogencarbonate is an acid salt formed by neutralization of a strong base and a weak acid, and is weakly alkaline when dissolved in water. 
When mass production of steamed bread, fritters and other foods, the soda powder melt water is often mixed into the surface, and then decomposed into sodium carbonate, carbon dioxide and water after heat, carbon dioxide and water vapor overflow, which can cause the food to be more fluffy, and the sodium carbonate remains in the food. in. Adding excess soda powder to the taro can be tasted.
