Question

How does volume change on mixing two volatile liquids to form ideal solution?

Answer 1

Both laws state that the partial pressure of the volatile component is directly proportional to its mole fraction in the solution. ... Characteristics of ideal solutions: Enthalpy of mixing (ΔmixH) of the pure components to form the solution is zero. Volume of mixing (ΔmixV) is also equal to zero.

Answer 2

THE VOLUME CHANGES ON MIXING TWO VOLATILE LIQUIDS TO FORM AN  IDEAL SOLUTION FOR THE FOLLOWING REASONS:

• The partial pressure of a volatile component in a solution is precisely proportional to its mole fraction in the solution, according to both laws. Ideal solution characteristics are: The pure components' enthalpy of mixing to generate the solution (mix H) is zero. Also zero is the volume of mixing (mix V).

• Because the density of volatile liquids is lower than that of an ideal solution, the volume of the solution will grow when they are mixed to make an ideal solution.
