Volumetric and Compressibility Studies of Some 1 : 1 Electrolytes in the Presence of Furosemide Using Transport Properties

Abstract

Abstract Sound velocities (v) and densities (d) for some alkali metal chlorides in aqueous solutions containing 0, 0.001, 0.005 and 0.01 M Furosemide have been measured at different temperature (293, 303 and 313 K). The data was used to apparent molar volume (ϕ v ) and apparent molar adiabatic compressibility (ϕ k ). The above calculated parameters were found to be sensitive to the prevailing in the Furosemide-Na+/K+-water system. These parameters have been examined as a function of Furosemide concentration and temperature to understand the consequences of interactions between these two components. Debye Hückel limiting law is used for the assessment of the contributions of various types of solute-solvent interactions. Viscosity B-coefficients have also been evaluated for these salts in the presence of Furosemide. Jones–Dole viscosity equation is used to calculate viscosity B-coefficient which is known to provide information concerning the solvation of ions and their effects on the structure of the solvent in the near environment of the solute particles. It is related to measure the solute–solvent interaction and is interpreted in terms of the solvent structure-making and breaking effect of the electrolyte in solution. A reasonably good qualitative correlation is found to exist with regard to the Furosemide-Na+/K+ interaction obtained from the experimental data, from different techniques.
