Palladium chloride, also known as palladium dichloride, palladium chloride and anhydrous chloride, is a reddish brown crystalline powder, which is easily soluble in dilute hydrochloric acid, water, ethanol, acetone and hydrobromic acid, and is easy to deliquesce in the air. Its purpose is to prepare special catalysts and molecular sieves; Preparation of non-conductive material coating; Make gas sensors, analytical reagents, etc.

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.
