Limit of solubility in the ternary liquid mixture. P3030601
You can get the concept of: Windows miscibility, phase diagrams, Law Gibb's.
Principle: A set of completely mixed two-component mixtures prepared for the study of a ternary system consisting of acetic acid, hloroformma and water. These mixtures are titrated against the third component, while two-phase system will not be formed, causing turbidity.
