Rapid prediction of refractive index and density of aqueous lithium iodate solutions. (English) Zbl 0898.92036
Summary: Quadratic equations to describe density and refractive index of aqueous Lithium Iodate solutions, which were originally proposed by J. Szewczyk and K. Sangwal [J. Chem. Eng. Data 33, 418-423 (1988)] do not adequately describe the effect of temperature as well as solute concentration. For accurate predictions of refractive indices and densities of aqueous Lithium Iodate solutions over the temperature range \(10^\circ\)C to \(60^\circ\)C and solute concentration range 0.01 to 3.0, a simple polynomial \(Y= K_1+ K_2(X-X_1)+ K_3(X-X_1)^p\) has been used.
