Solution
Raoult's law
“For a solution of volatile liquids, the partial vapor pressure of each component of the solution is directly proportional to its mole fraction present in solution”.
Ideal solution
"The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. "
Conditions for the ideal solution
Two important properties of an ideal solution are as follows:-
, and
Here, is the enthalpy of mixing of the pure components to form the solution.
is the volume of mixing.
Hence, the “ideal solution” term is used for the solution that obeys Raoult's law.
