The measurements on the conductivity of Sodium Chloridein pure water and ethanol-water mixed solvent media containing 0.10, 0.20, 0.30, 0.40 and 0.50 volume fractions of ethanol at room temperature are reported. The concentrations were varied from ~ 0.025 to~0.10 mol.L-1. The results showed a sharp increase in the conductivity with increasing electrolyte concentration. The effects of relative permittivity of the medium on the conductivity are also investigated.
