उत्तर
Definition:
The solutions that obey Raoult’s law over the entire range of concentration are called ideal solutions. Examples: n-hexane and n-heptane
For ideal solutions:
Enthalpy of mixing (Δmix H) of the pure components to form the solution is zero.
Volume of mixing (Δmix V) is also equal to zero.
