Abstract


The relative viscosities of formates of lithium, sodium, potassium. calcium and barium in formic acid have been determined at 30°C. The data has been analysed by Jones—Dole equation. The ionic B-coefficient values have been derived and quantitatively interpreted. Large and positive B-coeffieient values and large values of solute free energy of activation of flow parameter leads to the conclusion that the cations under study enhances theformic acid structure in the order: Ba 2 + > Ca2 + > K+ >Na 4 > Li. The solvation numbers of these ions in this solvent are also reported.

Keywords
