Study Notes

Triangle Representation

Each corner of the triangle represents 100% of one component (A, B, or C).
The same corner represents 0% of the other two components.
The area inside the triangle represents all possible combinations of the three components.

Point M

Point M represents a three-component system where X = 50% w/w, Z = 20% w/w, and Y = 30% w/w.

Experiment

The experiment uses Acetic Acid (HAC), Chloroform (CHCl3), and distilled water.
The experiment involves preparing various combinations of HAC and CHCl3 (5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90% w/w).
The experiment aims to obtain a miscibility curve by determining the percentage of each component in the turbid mixture.
Plotting the data on a triangular diagram will help visualize the results.
