Abstract
THE Werner formulation for the dark-green chromic chloride hexahydrate, namely, [CrCl2(H2O)4]Cl,2H2O, has been criticised recently by Britton (J. Chem. Soc., 1925, 127, 2128), who offers the alternative view that the basic chromium complexes apparently present in green solutions are “micellar” in structure and virtually constitute a colloidal electrolyte in which the cations are composed of chromium hydroxide and varying amounts of acid radical, a portion only being ionisable. This view accounts for the fact that green salts show greater resistance towards alkali than the analogous violet modifications.
