SOLUTIONS: IDEAL AND NON IDEAL SOLUTION

Ideal solution :-> The solutions which obeys raoult's law over entire range of concentration are known as ideal solutions.

* During mixing of two solution the enthalpy change and volume change must be equal to zero.

* Example:- chloromethane and bromomethane, Chlorobenzene and bromobenzene, benzene and Toluene.

Non- Ideal Solution :-> The solutions which does not obeys raoult's law over entire range of concentration are known as non-ideal solutions.

* During mixing of two solution there will be enthalpy change and volume change.

* Example:- Acetone and benzene, Acetone and chloroform.

* Non- Ideal Solution two types:-

(a) Positive Deviation

(b) Negative Deviation
