Raoult’s Law

01/07/26

“How can we determine the vapor content of a mixture?”

Vapors form above liquids. When two liquids mix, their vapor will also be a mixture. Raoult’s Law describes the content of the vapor mix, with each component proportional to the percentage makeup of the liquid multiplied by its saturation pressure. If a component has a high enough saturation pressure, then it can have a larger presence in the vapour compared to the liquid.
