Sodium Bisulfate

short description:

Sodium bisulphate, also known as sodium acid sulfate, is sodium chloride (salt) and sulfuric acid can react at high temperatures to produce a substance, anhydrous substance has hygroscopic, aqueous solution is acidic. It is a strong electrolyte, completely ionized in the molten state, ionized into sodium ions and bisulfate. Hydrogen sulfate can only self-ionization, ionization equilibrium constant is very small, can not be completely ionized.

Product Usage

MAIN USE

It is mainly used as a flux and disinfectant, and is used for sulfate and sodium alum, etc., and also used as a mineral decomposition flux, acid dye dyeing aid and sulfate and sodium vanadium, etc., and is also used in the manufacture of toilet cleaners, deodorants, disinfectants. Because it is an acidic salt, when it reacts with a base, it releases hydrogen ions, causing the pH in the solution to drop. This makes sodium bisulfate ideal for neutralizing alkaline wastewater. Secondly, sodium bisulfate can also be used as a food additive. It is widely used to make monosodium glutamate, soy sauce and other acidic foods. This is because it can regulate the acidity of the food, making the food more delicious. In addition, sodium bisulfate can also be used in metallurgy. It is widely used for leaching gold, silver, copper and other precious metals. This is because sodium bisulfate can form complexes with precious metals such as gold, silver, and copper, and then separate the precious metals through hydrolysis reactions. In addition, sodium bisulfate can also be used in the field of pharmaceutical production. It can be used to make some chemicals, such as taurine, cholic acid, inosine and blood pressure drugs. Sodium bisulfate is an important intermediate compound in the pharmaceutical manufacturing process. Finally, sodium bisulfate can also be used in chemical reactions in the laboratory. It can be used as a strong acid, is involved in many chemical reactions, and also has an important role in some purification processes. In general, sodium bisulfate is an important inorganic compound, which has a wide range of applications. From industry to medicine, from food to laboratories, it is needed to exist. It has made indispensable contributions to scientific and technological progress and social development in various fields.
