Study of molar refraction and polarisability constant of aqueous solutions of NH4NO3and KBrO3 at different temperatures

摘要

Densities and Refractive Indices of aqueous solutions of potassium bromate (KBrO 3 ) and ammonium nitrate (NH 4 NO 3 )h ave been studied with temperature in the range T= 298.15.K- 313.15.K. The data obtained is utilized to determine Specific Refraction (R D ) and Molar Refraction (R M ) of solutions. The values of Refractive indices, Molar Refraction (R M ) and Molar Polarisability (α) co nstant are found to be decreased with decreasing concentration of solute in solvent and these results are interpreted in terms of various interactions.
