You can get the concept of: Melting point, binary number system, Evtekticheskaya mixture, the Gibbs phase law.
Principle: The graph of cooling curves of binary mixtures can see the temperature of melting and solidification of samples with different molar mass fractions of these two components. In this experiment, determined the composition of evtekticheskoy mixture and its melting point based on the diagram the melting point.
