Miscibility gap in a ternary system

Article no: P3030601

Principle

A number of completely miscible two component mixtures are prepared to investigate the three component acetic acid / chloroform / water system. These mixtures are titrated with the third component until a two phase system is formed which causes turbidity. The phase diagram for the three component system is plotted in a triangular diagram.

Benefits

  • Good and reproducible results due to temperature control in the experiment.
  • Stable and safe construction due to solid stand material

Tasks

  1. Titrate nine different acetic acid / chloroform mixtures with water until a two phase system is formed in each case.
  2. Titrate six acetic acid / water mixtures with chloroform until phase separation is observed.
  3. Plot the results of the titrations, expressed as molar fractions, in a triangular diagram.

Learning objectives

  • Three component system
  • Miscibility gap
  • Phase diagram
  • Triangular diagram
  • Gibb's phase law

Necessary accessories

  • Chloroform
  • Precision balance 620g/0.001g
