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.

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.
