ideal and nonideal solutions

ldeal solutions: Solutions which obey Raoult's law strictly at all temperatures and concentrations are called ideal solutions Further the heat change (ΔH ) and the volume change (ΔV ) on mixing of such
solutions are zero. Actually, ideal solutions are very rare but many solutions .

e. g benzene & toluene, ethyl bromide and ethyl iodide, hexane & heptane practically behave as ideal.

Non-ideal solutions; Solutions which do not obey Raoult's law  and there is a  volume and heat energy when two  components are mixed are called non~ideal solutions e. g. ethanol and cyclohexane, benzene and acetone, acetone and cthroform etc.
