Formation constants for the cobalt(II) chloride-1-nitroso-2-naphthol system in ethanol-benzene mixtures

The values of conditional formation constants for the cobalt(II) chloride-1-nitroso-2-naphthol system were determined at 25° in ethanol-benzene mixtures of different compositions by spectrophotometry in the visible region. Comparisons were made with the results previously obtained with the isomeric...

Description
Summary:The values of conditional formation constants for the cobalt(II) chloride-1-nitroso-2-naphthol system were determined at 25° in ethanol-benzene mixtures of different compositions by spectrophotometry in the visible region. Comparisons were made with the results previously obtained with the isomeric ligand 2-nitroso-1-naphthol. In both cases the L/M complexation ratio of the species found increases with increasing ethanol content of the medium.
