Explanation:
Osmotic pressure is directly proportional to the degree of dissociation of a solute. Therefore, the salt with the highest degree of dissociation will have the highest osmotic pressure.
a) Decimolar Al2(SO4)3: This salt dissociates into 3 ions in solution: 2 Al3+ and 3 SO42-. Therefore, it has a higher degree of dissociation and hence higher osmotic pressure.
b) Decimolar BaCl2: This salt dissociates into 3 ions in solution: 1 Ba2+ and 2 Cl-. Therefore, it has a lower degree of dissociation and hence lower osmotic pressure.
c) Decimolar Na2SO4: This salt dissociates into 3 ions in solution: 2 Na+ and 1 SO42-. Therefore, it has a lower degree of dissociation and hence lower osmotic pressure.
d) A solution obtained by mixing equal volumes of (B) and (C) and filtering: This solution will contain both Ba2+ and SO42- ions. However, since BaSO4 is insoluble in water, it will not contribute to the osmotic pressure. Therefore, the osmotic pressure of this solution will be lower than that of (A).
Hence, option (A) Decimolar Al2(SO4)3 will have the highest osmotic pressure.
