Chapter 5, Problem 5E.4AE

(i)

Interpretation Introduction

Interpretation:

The number of phases for a system of ${\text{NH}}_{\text{4}}\text{Cl/}{\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{SO}}_{\text{4}}{\text{/H}}_{\text{2}}\text{O}$ at composition $\left(0.2,0.4,0.4\right)$ has to be stated.

Concept introduction:

The ternary system is defined as the system having three components.  These components in a mixture on undergoing the phase changes represent a triangular phase diagram.  Therefore, the three dimensional representation of the phase diagram is given for the ternary system.
