Conductometric studies of aqueous solution of thymine and adenosine at different temperatures

الملخص EN

Molar conductivity of different concentrations of thymine and adenosine in water, sodium acetate and ammonium chloride solution at different temperatures , 283.

15-323.15 K has been determined from direct conductivity measurements, examination of aqueous mixture of thymine and adenosine with Onsager equation reveal deviation from linearity at high concentration .This deviation was explained in term of molecular interaction .

Ostwald dilution law also examined with the above mixtures lead to calculation of limiting molar conductivities and dissociation constants of both nucleic acid in water , sodium acetate and ammonium chloride.

The agreement between the values obtained for Onsager equation and Ostwald law was reasonable.

Calculation of activation energies of flow using modified Arrhenius equation gives a result showed that the molecular interaction of both acids in all different mixtures were the same.
