Question

Which of the following aqueous solution shas osmotic presseure nearest to that of an equimolar solution of `K_(4)[Fe(CN)_(6)]`
A. `Na_(2)SO_(4)`
B. `BaCl_(2)`
C. `Al_(2)(SO_4)_(3)`
D. `C_(12)H_(22)O_(11)`

Answer 1

Correct Answer - C
We know that the value of collgative property is directly proportional to no. of particles of solute .Since`K_(4)[Fe(CN)_(6)]`and `Al_(2)(SO_(4))_(3)`both from `5` ion on dissociation .Hence osmotic pressure of `Al_(2)(SO_(4))_(3)`solution will be nearest to that of equimolar solution of `K_(4)[Fe(CN)_(6)]`
