Conclusion and Recommendation:

In this experiment, the group was able to analyze a phase diagram for a system of binary solids involving the formation of a compound. The diagram shows the state of the system on a graph of temperature versus the composition at constant pressure. As the group continues to cool the system, eventually, a temperature where one or both components freezes was reached. The freezing point decreases as it move away from either pure components. A line was drawn from the melting point of the pure substance through the freezing points to the eutectic point. The area below the freezing point line, but above the eutectic temperature represents a mixture of liquid melt and pure solid substance whose composition lies on the same side of eutectic composition.
