Raoults Law and the Ideal Solution

Equations (6.65) and (6.66) are statements of Raoult s law. They form the basis for defining an ideal solution. 

An ideal solution is one for which all components obey Raoult s law 

J A possible exception is a mixture of d and / optical isomers of a compound. 

We repeat that ideal solutions, like ideal gases, do not exist. But like the ideal gas, the ideal solution has an application as a reference state, and it is important to know the conditions under which Raoult s law is a good 

In a dilute solution the solvent approaches Raoult s law behavior.
