100 ml of a liquid A was mixed with 25 ml of a liquid B to give a non-ideal solution of A-B mixture. The volume of this mixture would be

For non-ideal solution volume will be either >125 or < 125. Hence volume of solution will be close to 125. 56. In case of positive deviation from Raoult’s law. Interaction of (a) A – B > A – A or B - B (b) A – B < A – A or B – B (c) A – B = A – A or B – B (d) None of the above In case of positive deviation from Raoult’s law, A- B(solute-solvent) interaction are weaker than those between A-A(solute-solute) or B-B(solvent-solvent).
