Sodium bicarbonate (Sodium bicarbonate), molecular formula NaHCO3, is an inorganic compound, white powder or fine crystals, odorless, salty taste, easily soluble in water, slightly soluble in ethanol (a said insoluble), aqueous solution is slightly alkaline. Decompose easily by heat, decompose slowly in humid air, produce carbon dioxide, decompose at about 50ºC, decompose completely when heated to 270ºC [1]. When it meets acid, it decomposes strongly and produces carbon dioxide. Sodium bicarbonate is widely used in chemical industry, food, light industry, textile and other industrial fields, as well as people's daily life, occupies an important position in the national economy.
laboratory use
Sodium bicarbonate can be used as an analytical reagent and also in inorganic synthesis. It can be used to prepare sodium carbonate-sodium bicarbonate buffer solution. When adding a small amount of acid or alkali, it can keep the hydrogen ion concentration from changing significantly and keep the pH value of the system relatively stable.
industrial use
Sodium bicarbonate can be used to produce acid-base fire extinguishers and foam fire extinguishers. In the rubber industry, sodium bicarbonate can be used in the production of rubber and sponges. In the metallurgical industry, sodium bicarbonate can be used as a flux for casting steel ingots. In the machinery industry, sodium bicarbonate can be used as a forming aid for cast steel (sand foundry) sand molds.
food processing purposes
In food processing, sodium bicarbonate is the most widely used loosening agent and is used in the production of biscuits, bread, etc. However, sodium bicarbonate will remain after the action. If used too much, the food will become too alkaline and the flavor will deteriorate. The color is yellowish brown.
medical purposes
Sodium bicarbonate can be used as a pharmaceutical raw material to treat hyperacidity and metabolic acidosis, and can also alkalize urine to prevent uric acid kidney stones.
