Apparent Molar and Partial Molar Volumes of Aqueous Ceric Ammonium Nitrate Solutions at 20, 25, 30, and 35°C

摘要

Present paper reports the measured densities (ρ) and refractive indices (n_D) of aqueous solutions of ceric ammonium nitrate (CAN) at 20, 25, 30, and 35°C in different concentrations of solution. Apparent molar volumes (φv) have been calculated from the density data at different temperatures and fitted to Massons relation to get limiting partial molar volumes (Ф_v~0) of CAN. Refractive index data were fitted to linear dependence over concentration of solutions and values of constant K and n_D~0 for different temperatures were evaluated. Specific refractions (R_D) of solutions were calculated from the refractive index and density data. Concentration and temperature effects on experimental and derived properties have been discussed in terms of structural interactions.
