Apparent molar and partial molar volumes of aqueous ceric ammonium nitrate solutions at 20, 25, 30, and 35°C

Abstract

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 (ϕ 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.
