Sodium bicarbonate, also known as baking soda or bicarbonate of soda, is an inorganic compound with the molecular formula NaHCO₃. Its appearance is white crystalline powder, odorless, salty, soluble in water. It decomposes slowly in humid air or hot air to produce carbon dioxide, and bicarbonate of soda will decompose completely when heated to 270°C. If it encounters acid, sodium hydrogen carbonate will decompose strongly and produce carbon dioxide. What’s more, sodium bicarbonate powder is widely used in analytical chemistry, inorganic synthesis, industrial production, agricultural and animal husbandry production, etc.
What Is Sodium Bicarbonate Powder Used For?
Sodium bicarbonate powder is mainly applied as food additive in food stuff industry, feed additives for animals, foaming agent in rubber industry, acidifying agent in medicine industry, compounding ingredient in detergent making, detergent in movie making, carbon Dioxide (CO2) reactor in beer,drinks,etc.
It can be used to produce acid-base fire extinguishers and foam fire extinguishers.
In the rubber industry, sodium hydrogen carbonate can be used in the production of rubber and sponge. In the metallurgical industry, bicarbonate of soda can be used as a flux for casting steel ingots.
In the machinery industry, bicarbonate of soda can be used as a molding aid for cast steel (foundation) sand molds.
In the printing and dyeing industry, sodium bicarbonate can be used as a color-fixing agent for dyeing and printing, an acid-base buffering agent, and a post-treatment agent for fabric dyeing and finishing. Adding sodium bicarbonate powder in the dyeing can prevent the bobbin from producing colored flowers, and it can also be used as a detergent for wool.
As loosening agent, sodium bicarbonate for sale can be used to produce biscuits, bread, etc. However, if it is used too much, the alkalinity of the food will be too high, which will cause the flavor to deteriorate and the color to be yellowish brown.
Bicarbonate of soda can be compounded with alum to make alkaline fermentation powder, and can also be compounded with soda ash to make civil lime.
Sodium hydrogen carbonate can be used as a color-protecting agent for fruits and vegetables in vegetable processing. When washing fruits and vegetables, adding about 0.1%~0.2% sodium bicarbonate can stabilize the green color.
When used as a treatment agent for fruits and vegetables, the pH value of fruits and vegetables can be increased by boiling and bleaching of fruits and vegetables, the water holding capacity of protein can be improved, the softening of food tissue cells can be promoted, and the astringent components can be dissolved.
It is the generator of carbon dioxide in soda drinks.
In addition, bicarbonate of soda also has the effect of removing taint from goat milk, and the dosage is 0.001%~0.002%.
Sodium bicarbonate can be used for soaking seeds in agriculture, and can also make up for the lack of lysine content in feed. Dissolving sodium hydrogen carbonate in a small amount of clear water or mixing it into the concentrate and feeding it to cattle (adding in an appropriate amount) can promote the growth of cattle, and at the same time significantly increase the milk production of dairy cows.
Sodium bicarbonate can be used as an analytical reagent and is also used in inorganic synthesis. It can be used to prepare sodium carbonate-sodium bicarbonate buffer solution. When a small amount of acid or alkali is added, it can keep the concentration of hydrogen ions from changing significantly, and keep the pH value of the system relatively stable.
Bicarbonate of soda can be used as a pharmaceutical raw material for the treatment of hyperacidity, metabolic acidosis, and alkalinization of urine to prevent uric acid kidney stones.
