Copper Chloride

Copper(II) chloride dissociates in aqueous solution to give the blue color of [Cu(H₂O)₆]²⁺ and yellow or red color of the halide complexes of the formula [CuCl_2+x]^x-. Concentrated solutions of CuCl₂ appear green because of the combination of these various chromophores. The color of the dilute solution depends on temperature, being green around 100 °C and blue at room temperature.^[2] When copper(II) chloride is heated in a flame, it emits a green-blue colour

Copper(II) chloride occurs naturally as the very rare mineral tolbachite and the dihydrate eriochalcite. Both are known from fumaroles. More common are mixed oxyhydroxide-chlorides like atacamite Cu₂(OH)₃Cl, arising among Cu ore beds oxidation zones in arid climate (also known from some altered slags).
