The measurement of density, conductivity, Viscosity, Surface tension and refractive index of aqueous solution of drug, Levofloxacin were carried out with the help of density bottle, conductivity meter, Stalagmometer and Refractometer at various temperatures. It was found that the values of apparent molar volume decrease by increasing temperature from (303 to 333)K.The value of Viscosity increase by increasing the concentrations from (0.0025 to 0.01) mol.dm-1 at all temperature. The increase in viscosity is due to extent of hydrogen bonding. The Rheochor values also increase by increasing the...
