The temperature-composition diagram, for the liquid-solid transformations in a binary system comprising A and B at 101.3
The temperature-composition diagram, for the liquid-solid transformations in a binary system comprising A and B at 101.3kPa, is shown below. (a) Label all phase regions on the diagram (b) Specify the melting points of pure A and pure B (c) What is the maximum solubility of (i) A in B, (ii) B in A ? (d) Starting from a temperature of 110∘C, at what temperature will a solid phase first appear in each of the following mixtures, when the mixtures are cooled slowly? (i) 30mass% (ii) 30mass% A ? (e) What is the composition of each of the solid phases in Part (d) above? (f) What are the compositions and proportions of all co-existing phases in a mixture containing 60 mass % B at a temperature of 82∘C ? Ans (b) 106∘C \& 100∘C, (c) 0% \& 20%, (d) (i) 98∘C, (ii) 88∘C, (o) (i) 10%,(it)100% (f) L(60%B,0),SA(20%,B,0.54),SD(100%6B,0.46)
