Standard Partial Molar Heat Capacities and Volumes of Barium and Cadmium Ions in Dimethylsulfoxide at 298.15 K

Abstract

The heat capacities and volumes of dimethylsulfoxide (DMSO) solutions of barium and cadmium iodides at 298.15 K were measured by calorimetry and densimetry. The standard partial molar heat capacities $$\bar {C}_{{p,2}}^{^\circ }$$ and volumes $$\bar {V}_{2}^{^\circ }$$ of BaI2 and CdI2 in DMSO were calculated. The standard heat capacities $$\bar {C}_{{p,i}}^{^\circ }$$ and volumes $$\bar {V}_{i}^{^\circ }$$ of barium and cadmium ions in DMSO at 298.15 K were determined.
