Ideal Binary Solution of Two Volatile Liquids
An ideal binary solution of two volatile liquids refers to a mixture of two liquids that obey Raoult's law.
Raoult's Law
Raoult's law states that the partial pressure of each component of an ideal mixture of liquids is directly proportional to its mole fraction in the solution.
a) Vapor Richer in More Volatile Component
For an ideal binary solution, the vapour is always richer in the more volatile component compared to the liquid. This is because the more volatile component has a higher vapour pressure, and hence, it evaporates faster and in greater amounts.
b) Gradual Enrichment of Liquid
If such a mixture is boiled or distilled, the liquid will gradually become richer in the less volatile component. This is because the less volatile component has a higher boiling point and hence, it takes longer to evaporate.
c) Total Pressure Above Solution
The pT (i.e. the total pressure) above the solution will be the sum of the vapour pressures of the two pure components. This is because each component contributes to the total pressure in proportion to its mole fraction in the solution.
d) Lower Boiling Point
The boiling point of the solution will be less than the boiling points of the two components. This is because the presence of the second component lowers the vapour pressure of the first component and reduces its boiling point.
Conclusion
In summary, an ideal binary solution of two volatile liquids obeys Raoult's law, and its vapour is always richer in the more volatile component. If such a mixture is boiled, the liquid will gradually become richer in the less volatile component. The total pressure above the solution is the sum of the vapour pressures of the two pure components, and the boiling point of the solution is lower than the boiling points of the two components.
