Determining maximum Osmotic pressure

Which of the following would have the maximum osmotic pressure (assume that all salts are 90% dissociated):

(a) Decimolar aluminium sulphate (b) Decimolar barium chloride (c) Decimolar sodium sulphate (d) A solution obtained by mixing equal of (b) and (c) and filtering

Answer: (a) Al2(SO4)3 Deci-molar gives maximum ion. Therefore, its osmotic pressure is maximum.
