The density and Viscosity of Ethanol-Water mixed solvent systems (5%, 10%, 20% ,40% v/v ) has been determined at 298,303,308 and 313 K. The same parameters has been determined for the KCl-Ethanol-Water mixture (2%, 4%, 6%, 8%, 10% w/v)The results obtained from these determinations were discussed. The effect of temperature and KCl electrolyte on density and viscosity of mixed solvent systems and mixture has been studied. The increase in temperature of mixed solvent system results in decrease in density and Viscosity. But with the addition of KCl electrolyte in mixed solvent system results in increase in density and viscosity at constant temperature but the same parameters decrease when temperature increases. The variation of these parameters is due to solute-solvent and solvent-solvent interaction.
