Question

From Physical Chemistry 8th edition by Atkins, Chapter 6

6.3 Draw phase diagrams for the following types of systems. Label the regions and intersections of the diagrams, stating what materials (possibly compounds or azeotropes) are present and whether they are solid liquid or gas. (a) Onecomponent, pressure–temperature diagram, liquid density greater than that of solid. (b) Two-component, temperature–composition, solid–liquid diagram, one compound AB formed that melts congruently, negligible solid–solid solubility.

Explanation / Answer

(a)

It is possible to get ice and water as an example for a system which the liquid density is greater than solid

(b) Two-component, temperature–composition, solid–liquid diagram, one compound AB formed that melts congruently, negligible solid–solid solubility.

e-Eutectic Point (The mixture with lowest temperature)

P-Phase
