The measurement of pressure exerted by a vapor is demonstrated using barometers. Vapor pressure varies with the strength of the intermolecular forces in the liquid.

In this section we will look at vapor pressure of mixtures. We can calculate the vapor pressure of a mixture using Raoult's law.

The probe from a digital thermometer touches the solid sodium acetate to test the temperature. It is seen that the material is quite warm. The process of crystallization is an exothermic process in which heat is given off to the surroundings.
A rubber bulb containing a small quantity of water is attached to an inverted flask full of ammonia gas. A long tube extends from within the inverted flask of ammonia into a large container full of phenolphthalein and water.
A separatory funnel, four round-bottomed flasks, and some tubing form a closed system. One end of the tubing is immersed in an acetic acid solution that contains universal indicator. The glassware has been filled with ammonia gas. The stopcock of the funnel is closed. A small amount of water is added to the funnel above the closed stopcock.
Note that this movie consists of brief snapshots of the experiment.
