Witrynaimpurities during freezing and melting under different experimental conditions is briefly discussed in the dilute limit. Then, methods are recommended for estimating the … WitrynaThe effect of the total impurity concentration cl1 is thus enhanced by the factor 1/F. This is often called Raoult’s law. Thus, for systems containing only impurities with 0 € 0 ki =, plots of temperature versus 1/F provide a direct measure of the impurity concentration, and extrapolations to 1/F = 0 can be used to determine Tpure.
