WHAT IS THE IDEAL SOLUTION?
In binary solution liquids, the interaction between molecules of components is similar to the interaction between molecules of different components.
The ideal solution obeys Raoult’s law under all temperature and concentration conditions; there is no change if mixing two components.
For example Bromobenzene and chlorobenzene, Benzene and Toluene
Raoult’s law is applicable for an ideal solution; component A is,
Above equation (1), taking logarithms of both sides and differentiating, we have,
or
From, the Gibbs-Duhem-Margules equation,
If we integrate equation (3), we get,
Here, lnK = integrating constant
Taking antilog on both sides of the above equation, we get
Equation (4) is Raoult’s law for component B.
Therefore, we found that component A obeys Raoult’s law in the binary solution, so component B also obeys Raoult’s law.
