Is there a connection between ideal solutions and the addition of volatile or non-volatile solute?
Asked by Somya Dubey | 23 Jun, 2013, 10:25: PM
answered-by-expert Expert Answer
When a solute is added to a solution, changes in the interactions take place between the molecules of the solute and the solvent  commonly reffered to as( A - A ) OR ( B - B) interactions.
 
A solution is Ideal only if its change in enthalpy , change in volume after mixing the two components are Zero & it obeys the Raoults Law as well .
 
Accordingly, after adding the solute, the ideal solution may show a positive or negative deviation depending upon thr changes in the interactions.
