Miscibility gap in a ternary system
Article No: P3030601
Unknown 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 Titrate nine different acetic acid / chloroform mixtures with water until a two phase system is formed in each case. Titrate six acetic acid / water mixtures with chloroform until phase separation is observed. Plot the results of the titrations, expressed as molar fractions, in a triangular diagram.
