When exposed to air, it is easily oxidized to green high-priced copper salts, which decomposes in the light and turns brown. It is stable in dry air and easily blue to brown when wet. When melting, it is iron-grey. It is rapidly oxidized into basic salt in the air when exposed, and it is green. It turns brown when exposed to light. It is rapidly hydrolyzed in hot water to form cuprous oxide hydrate and turns red. It reacts slowly with strong acid. A solution of Cuprous Chloride in hydrochloric acid can absorb carbon monoxide to form a complex cuprous carbonyl chloride [Cu2Cl2 (CO) 2 · 2H2O] (toxic!). When heated, the carbon monoxide can be released. If there is excess Cu2Cl2, the solution The absorption of CO is almost quantitative, so this reaction can be used to determine the amount of CO in mixed gas in gas analysis. Cuprous chloride is a covalent compound and its melt conductivity is poor. Measure the relative molecular mass of the vapor, confirm that its molecular formula should be Cu2Cl2, and usually write its chemical formula as CuCl
