Write a brief note on ideal solutions.

Explanation

An ideal solution is a solution in which each component (i.e) the solute as well as the solvent obeys the Raoult's law over the entire range of concentration .Practically no solution is ideal over the entire range of concentration .However when the concentration of solute is very low ,the dilute solution behaves ideally If the two components present in the solution (A and B) are identical in size structure and having almost similar intermolecular attractive forces between them (i.e. between A -A B-B and B-A) and then the solution tends to behave like an ideal solution
(i) For an ideal solution,
(i) there is no change in the volume on mixing the two components (solute & solvent )
(`V_("mixing") =0) `
(ii) there is no exchange of heat when the solute is dissolved in solvent `(H_("mixing ")=0) `
(iii) escaping tendency of the solute and the solvent present in it should be same as in pure liquids.
Examples for ideal solution: benzene & toluence , n-hexane & n-heptane,
