Question

What are non ideal solutions? Give example.

Answer 1

Non-ideal solutions by definition cannot be dealt with through Raoult's Law. Raoult's Law is strictly for ideal solutions only. A non-ideal solution. The interactions between the two types of molecules are weaker than interactions between acetone molecules (pure substance)

For Example, consider two components A and B to form non-ideal solutions. Let the vapour pressure, pure vapour pressure and mole fraction of component A be PA , PA0 and xA respectively and that of component B be PB , PB0 and xB respectivel

Answer 2

Answer:

These solutions exhibit two types of deviations from Raoult's law namely (a) positive deviation and (b) negative deviation.

These solutions give azeotropic mixture.
