Isentropic compressibility, shear relaxation time and Raman spectra of aqueous calcium Nitrate and Cadmium Nitrate solutions
Journal of Solution Chemistry, 2005Co-Authors: Nashiour Rohman, Abdul Wahab, Sekh MahiuddinAbstract:Speed of sound, viscosity and Raman spectra of aqueous calcium Nitrate and Cadmium Nitrate solutions were measured as functions of molality and temperature. The isentropic compressibility isotherms for both systems cross over in a narrow molality region. In comparison with Ca(NO3)2(aq) solutions, Cd(NO3)2(aq) solutions have lower isentropic compressibilities due to a lower charge to radius ratio. The observed Raman spectral changes in the ν3 (≈1400 cm−1) and ν4 (≈700 cm−1) modes with an increase in molality suggest that the symmetry of NO3− changes from D3h to C2v, and solvent-separated and/or solvent-shared ion pairs are formed in both systems. The results from plotting electrical conductivity versus shear relaxation time also imply that the influence of the solvent-separated and/or solvent-shared ion pairs begins ≈2.0 mol-kg−1 for these systems. The larger Δν values for the ν3 mode for Cd(NO3)2(aq) solutions indicate stronger solvent-separated and/or solvent-shared ion pairs formation in comparison to Ca(NO3)2(aq) solutions.

electrical conductivity viscosity and molar volume of potassium Nitrate lithium Nitrate Cadmium Nitrate tetrahydrate melt systems
Journal of Chemical & Engineering Data, 1997Co-Authors: Gautam Kalita, Nashiour Rohman, Sekh MahiuddinAbstract:Densities, viscosities, and electrical conductivity of potassium Nitrate + lithium Nitrate + Cadmium Nitrate tetrahydrate melt systems were measured as functions of temperature (≈292.15 ≤ T/K ≤ 363.15) and at various compositions x. The temperature dependence of viscosity and conductivity has been described by the Vogel−Tammann−Fulcher (VTF) equation. Molar volume data were fitted to an equation similar to the VTF equation based on the free volume model. Viscosity isotherms, unlike electrical conductivity, exhibit both negative as well as positive deviation from linearity as a function of composition. Mixed alkali effect in electrical conductivity has been observed under the isoviscosity condition. The onset of the mixed alkali effect has been explained in terms of the anion polarization model and complex ion of Cadmium.

hemi 4 carboxy methoxy phenyl sulfanyl acetato κ2o o hemi 4 carboxy methyl sulfanyl phenyl oxy acetato bis 1 10 phenanthroline κ2n n Cadmium ii 4 carboxy methoxy phenyl sulfanyl acetate dihydrate
Acta Crystallographica Section E: Crystallographic Communications, 2005Co-Authors: Lihua Huo, Shan Gao, Hui ZhaoAbstract:The reaction of Cadmium Nitrate with 4-(carboxymethoxy)phenylsulfanylacetic acid in the presence of phenanthroline at a pH of 6 affords the salt, [Cd(C10H9O5S)(C12H8N2)2](C10H9O5S)·2H2O. The Cd atom in the cation is chelated by two phenanthroline units and one carboxylate from the monoanionic ligand in a distorted octahedral geometry. The coordinated monoanion shows disorder which results in a 50:50 mixture of 4-(carboxymethoxy)phenylsulfanylacetate and 4-(carboxymethylsulfanyl)phenyloxyacetate coordinated to the Cadmium. The cation and uncoordinated anion interact to form a linear chain.
