Chemical Reports

Ntshingila S.T Experiment 3: Liquid-vapour equilibrium
10312260 Group B3

Title
Use of methanol-methylene chloride system sort diagram to determine the boiling intend composition of a binary system
Abstract
By making use of the refractive magnate and mol fraction graph, it was possible to determine the boiling lead composition, further observation lead to the discovery that the refractive ability is higher when the composition has a low boiling point and vice versa. The different compositions have varying boiling points and hence depending on the different molar fractions and boiling points of the compounds, the refractive mogul will be influenced accordingly.
Results
Density: Methanol -0.791 g/ml
methylene radical-chloride-1.325 g/ml
1. Table of mixtures for the determination of the refractive index composition proportion:
Mixture fare| Composition| Refractive index|
| Methanol-cm3| Methylene chloride-cm3| |
A1| 5| -| 1.3281|
A2| -| 5| 1.4227|
A3| 5| 1| 1.3357|
A4| 4| 2| 1.
