Conductometric Studies on Solvation Behaviour of Dimethyl Ammonium Hydrochloride in Dmf and Water Mixture at Different Concentrations and Temperatures

S. K. Chavan and M. N. Hemade

This paper presents the measurement and analysis of the solvation behaviour of dimethyl ammonium hydrochloride in solvent mixture of DMF and water in varying compositions as a function of temperature. The data has been analysed by the Debye-Huckel-Onsager model and the Kraus-Bay equation. The limiting molal conductance as well as the dissociation constant has been calculated from the respective methods. These methods have been used to interpret the preferential / selective solvation of cations by the DMF. The Walden Product under prevailing conditions has also been computed and the effect of variation in temperature on the conductance has been identified. These data have been used for the qualitative study of ion-solvent and solvent-solvent interactions in the system.
