Sodium Bicarbonate Urine

Sodium bicarbonate

Specification

Sodium bicarbonate (Sodium bicarbonate), formula NaHCO₃, is an inorganic compound, white powder or fine crystal, odorless, salty, easily soluble in water, slightly soluble in ethanol (said to be insoluble), the solution is slightly alkaline. It is easily decomposed by heat, slowly decomposed in humid air, producing carbon dioxide, which begins to decompose at about 50 ° C, and is completely decomposed by heating to 270 ° C. When exposed to acid, it breaks down strongly, producing carbon dioxide.

Application

Laboratory use
Sodium bicarbonate can be used as an analytical reagent and is also used in inorganic synthesis. Can be used to prepare sodium bicarbonate-sodium bicarbonate buffer solution, adding a small amount of acid or base can keep the hydrogen ion concentration does not change significantly, can keep the pH value of the system relatively stable.
Industrial use
Sodium bicarbonate can be used in the production of acid-base fire extinguishers and foam fire extinguishers, and sodium bicarbonate can be used in rubber and sponge production in the rubber industry. Sodium bicarbonate can be used as a flux for casting ingot in metallurgical industry. In the machinery industry, sodium bicarbonate can be used as a molding aid for casting steel (foundry) sand. In printing and dyeing industry, sodium bicarbonate can be used as fixing agent for dyeing and printing, acid-alkali buffer, and rear treatment agent for fabric dyeing and finishing. The addition of baking soda to dyeing can prevent the yarn from producing colored flowers, and can also be used as a detergent for wool.
