STUDY OF MOLAR REFRACTION AND POLARIZABILITY CONSTANT OF AQUEOUS SOLUTIONS OF KNO3 AND KBrO3 AT DIFFERENT TEMPERATURES.

Abstract

Densities and Refractive Indices of aqueous solutions of potassium bromate (KBrO3) and ammonium nitrate (NH4NO3)have been studied with temperature in the range T= 298.15˚K- 313.15˚K. The data obtained is utilized to determine Specific Refraction (RD) and Molar Refraction (RM) of solutions. The values of Refractive indices, Molar Refraction (RM) and Molar Polarisability (α) constant are found to be decreased with decreasing concentration of solute in solvent and these results are interpreted in terms of various interactions. Keywords: Refractive index, Molar Refraction and Molar Polarisability. I.
