MAGNETO-OPTIC STUDY OF SOME INORGANIC ACIDS AND THEIR SALTS

Abstract

Measurements have been made of the optical and magneto-optic constants of aqueous solution of HN03, H2SO4 HCIO4 and H3PO4 and some of their salls at different concentrations. From the observed data the constants for the ions in solution have been evaluated. It is found that while the dispersion in the acids increases, the Verdet conSlant decreases with concentration. This effect has been attributed to the presence of near U.V. bands which contribute towards dispersion but not towards Faraday rotation. The magneto-optic anomaly factor for these acids is very low; y (HNO3) = 0.2, y (HCIO4) = O· 38, y (H2SO4) =0·53  y(H3PO4) = 0·62. and the y value for the ions changes considerably with concentration.
