Abstract

Molecular Interactions Of Aqueous Formic Acid

Author(s): Narain Datt Kandpal, B.K.Joshi

Measurements of density, viscosity and molecular conductance were performed on aqueous formic acid solutions of different concentration at 293 K. The apparent molar volume and coefficient of Jone-Dole equation have been calculated from density and viscosity data. The behaviour of these parameters suggests the ion-solvent interaction in the system and formic acid acts as “structure maker”. The presence of ionion pair in the system has been concluded from the conductance data. The results were also discussed in the light of Jone-Dole equation with modification and Grunberg-Nissan equation.
