Answer to Question #94259 in Physical Chemistry for Abhishek

Question

Draw a labelled phase diagram of Bi - Cd system.

Answer 1

Solution.

Point E on the graph means eutectic. A eutectic or eutectic mixture is a non-invariant (at constant pressure) point in a system of n components, in which n solid phases and a liquid phase are in equilibrium. The eutectic composition is a liquid solution that crystallizes at the lowest temperature for the alloys of this system. Accordingly, the melting temperature of the alloy of the eutectic composition is also the lowest, in comparison with alloys of a different composition for this system of components. This phenomenon just reflects the etymology of the term.
