Raoult's Law, Dalton's Law are used to explore what happens on mixing two liquids i.e. volatile solutes interact with volatile solvents. The effect on the overall vapour pressure, and hence boiling points is discussed here along with graphs for ideal solutions. Courses on Khan Academy are always 100% free.
