Abstract: Dielectric constant of binary mixtures has been carried out at low frequency at different temperatures. The liquids used in the study were ethanol, methanol and sodium chloride. To confirm interaction, orientation of the dipoles and intermolecular interaction between the mixtures the excess dielectric constant, Kirkwood correlation factor and Bruggeman factor of the mixtures have been calculated and reported in the study. The measurements have been carried out at 100 MHz frequency using a wet sensor. The dielectric constant of the binary mixtures increases with increasing the concentration of the NaCl and decreases with increase in temperature. The results also show the presence of intermolecular interaction in the mixtures.
