The bismuth-cadmium phase diagram is of interest in metallurgy, and its general form can be estimated from expressions for the depression of freezing point. Construct the diagram using the following data: Tf (Bi) = 544.5 K, Tf (Cd) = 594 K, ?fus H(Bi) = 10.88 kJ mol?1, ?fusH(Cd) = 6.07 kJ mol?1. The metals are mutually insoluble as solids. Use the phase diagram to state what would be observed when a liquid of composition x(Bi) = 0.70 is cooled slowly from 550 K. What are the relative abundances of the liquid and solid at (a) 460 K and (b) 350 K? Sketch the cooling curve for the mixture.
