The object of this book is to present the more important experimental results and theories relating to the electrolytic conductance of citric acid in solvent mixtures. Here, the measurements of viscosity, density and conductivity of Citric acid on aqueous DMF and DMSO at different temperatures. Limiting molar conductance, dissociation constant, Walden product, energy of activation have been calculated to detect solute – solute, solute- solvent and solute- solvent interaction. To explore the new insight of solute and solvent interactions in the solutions this book will stand as land mark. It contributes in the rapidly advancing knowledge of solution chemistry.
