100 mL of liuqid 'A' was mixed with 25 ml of a liquid 'B' to give a non-ideal solution of A-B mixture showing (-) ve deviation from Raoult's law. The volume of this mixture would be
75 mL
125 mL
close to 125 mL, but not exceeding 125 mL
just more than 125 mL
Solution
When two liquids form a non-ideal solution which exhibits a (-) ve deviation from Raoult's law, the volume change on mixing the two components is always negative, i.e., . Hence, the volume of solution cannot be equal to or greater than 125 mL, but is slightly less than 125 mL.
