From a systematic study of the temperature-variation of ultrasonic velocity and density in organic liquids, Rao has found that the ratio of the temperature coefficients of the ultrasonic velocity and density is nearly equal to 3 for most organic liquids. From this result he has deduced the relation: R = M/ρ (V)1/3 where M is the molecular weight, ρ is the density, V is the ultrasonic velocity and R, known as molar sound velocity, is characteristic of the liquid and is independent of temperature. Although Rao established this relation in the case of organic liquids, later workers have extended it to several inorganic liquids and have shown that R is independent of temperature. In the present communication, results are given of the variation with temperature of ultrasonic velocity in five molten hydrated salts.
