Sodium bisulfate (chemical formula: NaHSO4), also known as acid sodium sulfate, niter cake. Its anhydrous matter is hygroscopic. Sodium bisulfate decomposes into sodium pyrosulfate before reaching its melting point, so its melting point is difficult to determine. The aqueous solution of sodium bisulfate is acidic, and the pH of 1mol / L solution is about 1.4. In some cases, sodium bisulfate solution can be used instead of 39.0-42.0% sulfuric acid solution. For example, acetic acid can be obtained by distilling the mixed solution of sodium bisulfate and sodium acetate, and the sodium bisulfate solution can also react with most carbonates to produce carbon dioxide. To some extent, sodium bisulfate shows the properties of sulfuric acid and sodium sulfate mixture. This can be reflected when sodium bisulfate is dissolved in ethanol (it will decompose into sulfuric acid soluble in ethanol and sodium sulfate insoluble in ethanol). 2NaHSO4 → Na2SO4 + H2SO4

Sodium fluoride is an important fluoride product, widely used in wood preservatives, wine fungicides, electrolytic aluminum regulator, dental fluoride and other fields. Adding sodium fluoride to toothpaste can prevent caries. Fluoride and enamel can form fluorapatite on enamel surface, improve the hardness and acid resistance of enamel, and reduce plaque formation, reduce the incidence rate of dental caries.

Sulfur is an essential element for all life, and is widely used in biochemical processes such as metabolic reactions. Elemental sulfur is mainly used as a precursor to other chemicals such as sulfuric acid. Sulfur is increasingly used as a component of fertilizers. It can be used as an ingredient of Pesticide as well.

This product can be used as an analytical reagent for infrared detection of IR. It can also be used as an emulsion or developer for cine film and photographic film. It can also be used as a tranquilizer in medical treatment.

Used as photographic fixer, metal cleaning agent, electroplating solution and reducing agent.
