Ideal Solutions Chemistry Notes
→ Those solutions which obey Raoult’s law at all ranges of temperature and concentration are called ideal solutions. An ideal solution of components A and B will satisfy the following conditions: (1) It obeys Raoult’s law i.e,
→ The volume of solution on mixing both components should be equal to volume of two components. i.e.,
∆V(mixing) = 0
→ There is no change in enthalpy on mixing both components.i.e.
∆H(mixing) = 0
→ The intermolecular forces of attraction between A – B in solution should be equal to intermolecular forces of attraction present in components (i.e, between A – A and B – B). Solute and solvent having same physical and chemical properties form ideal solution.
