Define an ideal solution and write one of its characteristics.

Definition:  The solutions that obey Raoult’ s law over the entire range of concentration are called ideal solutions. Examples:  n-hexane and n-heptane.

Characteristics: For ideal solutions: 

 Enthalpy of mixing (_mixH) of the pure components to form the solution is zero.

The volume of mixing (_mixV) is also equal to zero.
