Physicochemical interactions between alkali metal oxalates and the uric acid (UA) were studied using easily available techniques such as density, viscosity and refractive index studies at three different temperatures. The values of limiting molar volume (Φ_V⁰), experimental slopes (S_V^*) were calculated from the density values using Masson equation to interpret the solute- solvent and solute – solute interactions respectively. Using Jones-Dole equation viscosity A and viscosity B co-efficient were calculated to support the solute- solvent and solute – solute interactions obtained from density measurement. Again the studies were supported by the result obtained from the refractive index studies. Lorentz-Lorenz equation was used to calculate the molar refraction (RM) values for refractive index studies.
