Sodium bicarbonate information
[Chemical name] Smooth soda/NAHCO3 (molecular)/sodium bigarbonate ( English name)[Product appearance] White fine crystal
[Property properties] Sodium bicarbonate is white crystals, or opaque monocliplastic crystals. The proportion is 2.15. Wasteless, salty, soluble in water, slightly soluble in ethanol. Its aqueous solution is slightly alkaline due to hydrolysis, and the nature of the normal temperature is stable. It is easily decomposed by heating. It gradually decomposes above 50 ° C. There is no change in the dry air and slowly decompose in the humid air. Solubility: Easy dissolution, 7.8g, 18 ℃; 16.0g, 60 ℃.
Heat is easy to break down. Slowly decompose in humid air. All of them become sodium carbonate at 100 ° C. It is quickly decomposed in weak acids, and its aqueous solution starts to decompose carbon dioxide and sodium carbonate at 20 ° C, and it is completely decomposed when the boiling point is. At 25 ° C, it is dissolved in 10 parts of water, and it is dissolved in 12 parts of water at about 18 ° C. The solution made of cold water without stirring has a slightly alkaline reaction to the phenolic test strip, placed or increased temperature, and its alkaline increases. The pH value of the 0.1mol/L water solution freshly prepared at 25 ° C is 8.3. Low toxic, half of the death (mice, meridian) 4420 mg/kg.

[Product purpose]
1. It is the most widely used loose agent in the food industry. Carbon dioxide incidence in soda beverage. The heating of sodium bicarbonate produces carbon dioxide gas
2. It can be compounded with alum as alkaline fermented powder
3. Washing agent used as wool.
4. For tanning, mineral selection, smelting, metal heat treatment, etc.
5. Fire -fighting equipment is used to produce pH fire extinguishing agents and foam fire extinguishing agents.
Al2 (SO4) 3 + 6NAHCO3 \u003d 3NA2SO4 + 2AL (OH) 3 \u0026 Darr; + 6CO2 \u0026 Uarr; aluminum hydroxide is covered on the surface of the burial, isolates the air, and
CO2 does not support combustion, It can also extinguish the fire.
6. The rubber industry uses it to cooperate with the alum and H -hair pores to produce even the production of even pores for rubber and seal production.
7. Metallurgical industry for melting agent for casting steel ingots. The mechanical industry is used as a molding assistant for cast steel (sandwiches) sand.
8. Printing and dyeing industry for staining stamps, acid -base buffer, and tidal treatment agent for fabric dyeing.
9. Foam agent, the principle of the use of baking soda high temperatures can be released
10. Decarnia. Because the main product of sulfur sulfur is sodium nitrite, the application of the glass industry The prospects are relatively wide.
11. Add sodium bicarbonate to the feed, which can supplement poultry to reduce the carbonate in the blood due to hot breathing (exhaled too much CO2), thereby improving the body's calcium metabolism.
12. Adding sodium bicarbonate in the feed can improve the mobility of phosphorus in eggs and poultry, so that the concentration of egg poultry blood phosphorus is maintained at the best level necessary for the formation of eggshells.
13. Add sodium bicarbonate to the feed to provide sodium sources to keep the blood concentration appropriate.
