The paper deals with the calculation of molar refraction () and polarizability () of antibiotic drug ciprofloxacin hydrochloride ( = 0.001–0.029 mol·dm−3) solutions in ethanol-water mixtures of different compositions (30, 50, and 70% v/v) from measured density () and refractive index () at 30°C. The effect of drug concentration and composition of ethanol-water mixtures on density and optical properties of drug solutions has been described.
