Here is reported evidence from viscosity data for competitive, reversible complex formation between species of Sn(IV) or Sn(II) and Sn(IV) or methanol in methanol – carbon tetrachloride solutions of SnCl4.5H2O and SnCl2.2H2O. Empirical relations between the viscosity parameter and the salt or methanol concentrations are also reported.

Spectrophotometric measurements on solutions of stannic iodide were found to provide evidence for complex formation with aromatic hydrocarbons. Calculations, based on spectra for mixed solutions of benzene and stannic iodide in carbon tetrachloride, yield values of 0.26 for the equilibrium constant (mole fraction), 28 400 1/mole cm for the molar extinction coefficient of the benzene – stannic iodide complex. Kinetic evidence indicates that the order of decreasing complex stabilities is from xylene to toluene to benzene. The formation of stannic iodide – aromatic hydrocarbon complexes provides an explanation for the discrepancy between measured solubilities of stannic iodide in benzene, toluene, and xylene, and the solubilities predicted by the Hildebrand theory of regular solutions.

Experimental Values

Densities, ultrasonic speeds and viscosities have been measured for benzyl alcohol, ethanol, propan-1-ol, octan-1-ol and for their binary mixtures with benzyl alcohol as common component at 303 K. From the experimental data, isentropic compressibility, relative association, acoustic impedance, molar sound velocity, excess volume, excess isentropic compressibility, deviations of viscosity and ultrasonic speed from linear dependence on composition, excess acoustic impedance and molecular association for all the three binary mixtures were obtained. These parameters have been interpreted in terms of intermolecular interactions. The experimental viscosity data of the three binary mixtures were used to test the validity of the empirical relations of Grunberg-Nissan, Tamura-Kurata, Hind-Mclaughlin, Katti-Chaudhary and Heric. The experimental values of ultrasonic speeds have been compared with those predicted on the basis of the Nomoto empirical relation, collision factor theory, free length theory and van Dael and Vangeel ideal mixing relation. The relative merits of these theories and relations are discussed.
