Abstract

Refractive indices and Densities of different concentrations of Potassium salts like KCI, KBr, and KI in Percentage of 10, 20, 40 and 60 (v/v) ethanol-water were measured at 303.15 K. Specific Refraction (R) were calculated by using Lorentz and Lorenz (L-L), Andher Desai and Joshi (ADJ), Chavda Desai and Joshi (CDJ), Damor Desai and Joshi (DDJ), Gadhawala Desai and Joshi (GDJ), Patel Desai and Joshi (PDJ. It is observed that the refractive indices increased with an increase of percentage of ethanol as well as with the concentrations of potassium salts for given compositions of binary solvent mixtures). It is also observed that the calculated specific refraction values of the all formulae give in increasing of the binary (Ethanol+Water) mixtures.
