ABSTRACT:

The refractive indices of liquid mixtures were measured with the help of Abbe’s refractometer, specially designed to measure the refractive indices of the small quantities of the transparent liquids and solutions by direct reading. In present work molar refraction and polarizability constant of o-amino-benzene sulphonic acid, 6, 7-dihydroxy naphthalene-2-sulphonic acid, 4-amino-3-naphthol-sulphonic acid at different concentrations and in the different percentage of dioxane-water mixtures were determined. Also the molar refraction and polarizability constants of 6, 7-dihydroxy naphthalene-2-sulphonic acid were measured in different solvents. The results are used to make the conclusion about molecular interactions.
