To determine the correct sequence of osmotic pressure for the given solutions, we need to calculate the van 't Hoff factor (i) for each solute. The osmotic pressure (π) is directly proportional to the product of concentration (C), the gas constant (R), temperature (T), and the van 't Hoff factor (i). Since the concentration, R, and T are constant for all solutions, we can focus on the van 't Hoff factor (i) to determine the osmotic pressure. ### Step-by-Step Solution: 1. **Identify the dissociation of each solute:** - **(a) Al₂(SO₄)₃:** - Dissociates into: 2 Al³⁺ + 3 SO₄²⁻ - Total particles after dissociation = 2 + 3 = 5 ...

Addition of non-volatile solute to a solvent always inceases the colligative properties such as osmotic pressure, DeltaP, DeltaT_(b) and DeltaT_(f) . All these colligative properties are direactly propertional to molality if solutions are dilute. The increase in colligative properties on addition of non-volatile solute is due to incease in number of solute particles. For different aqueous solutions of 0.1 N NaCl, 0.1 N urea, 0.1 N Na_(2)SO_(4) and 0.1 N Na_(3)PO_(4) solution at 27^(@)C , the correct statement are : (P) The order of osmotic pressure is, NaCl gt Na_(2)SO_(4) gt Na_(3)PO_(4) gt urea (Q) pi = (DeltaT_(b))/(K_(b)) xx ST for urea solution (R) Addition of salt on ice increases its melting point (S) Addition of salt on ice brings in melting earlier
