Question
Identify the false statement :
Options
A.The volume of a solution cannot be less than the sum of volumes of the pure solvent and solute used to prepare the solution (binary solution of two liquids)
B. At constant T and P, ᐃGmix will be necessarily negative for an ideal solution
C.An ideal binary solution (poA ≠ poB) cannot form an azeotropic mixture.
D.In binary solutions ideality is more of an exception rather than a rule.
Solution
(A) as in case of negative deviation.
(B) ᐃGmix is generally positive.
(C) Ideal mixture follows Raoult′s law at all compositions, so can not form a constant boiling mixture.
(D) It is theoretically impossible to obtain an ideal solution.
