Abstract
Measurements of the magnetic susceptibilities of mixtures consisting of binary combinations of carbon tetrachloride, benzene and nitrobenzene, made with the improved manometric balance of Wills and Boeker over the range of temperatures from 10°C to 50°C, are described. The results for mixtures of benzene and nitrobenzene, each of which shows no variation of mass susceptibility with temperature, show that the principle of additivity of susceptibilities is valid within the limits of precision of measurement. For mixtures of either benzene or nitrobenzene with carbon tetrachloride, a systematic deviation from additivity is found. The deviations for both groups show a definite dependence upon both concentration and temperature.
