  One, cuprous chloride:

  Cuprous chloride is a white cubic crystal or white powder. Slightly soluble in water, water-soluble at 0.06g/L (25℃), soluble in ammonia water to form a complex, soluble in concentrated hydrochloric acid to form H3CuCl4, also soluble in sodium thiosulfate solution, NaCl solution and KCl solution form the corresponding coordination It is insoluble in ethanol. The relative density is 4.14. The melting point is 430°C. The boiling point is 1490°C.

  The hydrochloric acid solution of CuCl can absorb carbon monoxide to form the compound cuprous chlorocarbonyl [Cu2Cl2(CO)2·2H2O] (toxic!), which can release carbon monoxide when heated. If there is excessive Cu2Cl2, the solution will affect CO Absorption is almost quantitative, so this reaction can be used to determine the amount of CO in mixed gases in gas analysis. CuCl is a covalent compound, and its melt conductivity is poor. Measure the relative molecular mass of its vapor and confirm that its molecular formula should be Cu2Cl2, and its chemical formula is usually written as CuCl.

  is stable in dry air, but will easily turn blue to brown when wet. It is iron-gray when molten. When exposed to the air, it quickly oxidizes to basic salt, which is green. It turns brown when exposed to light. It is rapidly hydrolyzed in hot water to form cuprous oxide hydrate, which is red and reacts slowly with strong acid.

  Two, use

  Cuprous chloride can be used as a catalyst for organic synthesis and used in industries such as pigments and corrosion protection.
