Refractive indices of different concentrations (5 ppm up to 200 ppm) of reference chemical solution (Fe(NO3)3) Nonahydrate were determined with an accuracy of ±10-5, the Brix of these chemicals were measured by using Digital multi-wavelengths (refractometer DSR-λ). Practically, the refractive indices of these solutions have been measured as a function of temperatures in the spectral visible range 0.4-0.7 μm; with increasing wavelengths and with increasing temperature the refractive index decreased monotonically. The refractive indices are increasing with increasing concentrations. Also, the Brix of this solution have been measured as a function of temperature (20 οC up to 30 οC) with wavelengths in the same visible spectral range. The Brix values are used as a tool of concentration of these chemicals samples. The empirical formula between the concentration and the Brix of these chemical are applied.

The modeling of the refractive index for binary aqueous solutions of boric acid, sodium chloride, potassium chloride, sodium sulfate, lithium sulfate, and potassium sulfate, as well as ternary aqueous solutions of boric acid in the presence of sodium sulfate, lithium sulfate, or potassium chloride, is reported. The refraction index was represented by molar refraction. It was described as the sum of solutes’ partial molar refraction and solvent molar refraction. The solutes’ partial molar refraction was estimated from the molar refraction of the binary solutions. The excess molar refraction for these systems was described with the equation of Wang et al. The polarizability of the solutes present in the studied systems was estimated using the Lorenz–Lorenz relation. The results showed the model is appropriate for describing the systems studied; the interactions of boric acid, sodium, potassium, lithium, chloride, and sulfate ions with water molecules are relevant to explain the molar ...

Theoretical Evaluation of Refractive Index in Binary Liquid Mixtures2005 •
The density and refractive index (RI) for four binary liquid mixtures: diethyl malonate + dimethylformamide (DEM+DMF), diethyl malonate + Hexane (DEM+HEX), diethyl malonate + tetrahydrofuran (DEM+THF), diethyl malonate + 1,4-dioxane (DEM+DO) have been measured. The experimental values are compared with those calculated from Lorentz-Lorentz, Heller, Newton and Gladstone -Dale mixing rules.
