Consider the two solutions
I. 0.5M NaCl aqueous solution at `25^(@)C`, NaCl is complete ionized
II. `2.0M C_(6)H_(5)COOH` in benzene at `25^(@)C, C_(6)H_(5)COOH` dimerizes to the full extent.
Which of the following statement(s) is (are) correct ?

A

Both the solutions display equal osmotic pressure

B

Both have equal vapour pressure

C

Solution II is hypertonic

D

Solution II has greater depression in freezing point than solution I

Text Solution

Verified by Experts

The correct Answer is:
A, D
NaCl: 0.5 M (i=2) `rArr C_("eff") = 0.5 xx 2= 1M`
`C_(6)H_(5)COOH : 2.0M (i= (1)/(2)) rArr C_("eff") =2 xx (1)/(2) =1M`
(A) `pi= C_("eff") RT rArr pi` is same as `C_("eff")` is same.
(B) Since both the solutions have different solvents, vapour pressure will be different.
(C ) Solution are isotonic
`Delta T_(f)= iK_(f)m rArr Delta T_(f)` for solution II will be more as `(K_(f))_("benzene") gt (K_(f))_("water")`
