Boiling point diagram of a binary mixture

Product No: P3030401

Principle

A boiling point diagram shows the boiling points of a binary mixture as a function of the vapour / liquid equilibrium of the mixture at constant pressure. The boiling points of various mixtures of methanol and chloroform are measured and the composition of the liquid phases are determined using refractometry and a calibration curve.

Tasks

Determine the refractive indiced of the pure components and about 10 different mixtures of known composition.
Plot the boiling point diagram of the binary mixtured of methanol and chloroform.

What you can learn about
