MCQ
The osmotic pressure of which solution is maximum (consider that deci-molar solution of each $90\% $ dissociated)
  • ✓
    Aluminium sulphate
  • B
    Barium chloride
  • C
    Sodium sulphate
  • D
    A mixture of equal volumes of $(b) $ and $ (c)$
✓

Answer

Correct option: A.
Aluminium sulphate
a
(a)$A{l_2}{(S{O_4})_3}$ gives maximum osmotic pressure because it is gives $5$ ion.
