Interaction studies of dilute aqueous oxalic acid

Abstract

Molecular conductance λm, relative viscosity and density of oxalic acid at different concentration in dilute aqueous solution were measured at 293 K. The conductance data were used to calculate the value association constant. Viscosity and density data were used to calculate the A and B coefficient of Jone-Dole equation and apparent molar volume respectively. The viscosity results were utilized for the applicability of Modified Jone-Dole equation and Staurdinger equations. Mono oxalate anion acts, as structure maker and the solute-solvent interaction were present in the dilute aqueous oxalic acid.
