The magneto-optic anomaly of electrolytes in aqueous solution

The Verdet constant and dispersions of 4-normal solutions of seventeen univalent halides have been measured. From these, the values of the magnetooptic anomaly have been estimated. The magneto-optic anomaly of the free ions of the alkali halides as distinct from that of the solution have been evaluated. It is found that the value of the anomaly of the free ions having the inert gas configuration is very near the theoretical value of 1. The ionic dispersivity and rotativity of the individual ions have been estimated. It is found that the additivity rule is approximately valid. The pure acids, HCl, HBr and HI, have values of the anomaly much lower than those for their solutions. This has been attributed to the presence of covalent linkages in the acids in the pure state. The anomaly for the rare gases neon and argon are very nearly unity. It is found that the values of molecular refractivity, dispersion, rotativity, rotation and the magneto-optic anomaly of the ions in solution are higher than those for the ions in the crystalline state.
