For different aqueous solutions of 0.1M urea, 0.1M NaCl, 0.1M Na_(2)SO_(4) and 0.1M Na_(3)PO_(4) solution at 27^(@)C , select the correct statements:

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

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 : 1g mixture of glucose and urea present in 250 mL aqueous solution shows an osmotic pressure of 0.74 atm at 27^(@) C . Assuming solution to be dilture, which are correct ? (P) Percentage of urea in solute mixture is 17.6 (Q) Relative lowering in vapour pressure of this solutions is 5.41 xx 10^(-4) . (R) The solution will boil at 100.015^(@)C , if K_(b) of water is 0.5 K "molality"^(-1) (S) If glucose is replaced by same amount of sucrose, the solution will show higher osmotic pressure at 27^(@)C (T) If glucose is repalced by same amount of NaCl , the solution will show lower osmotic pressure at 27^(@)C .

Addition of non-volatile solute to a solvent always increases the colligative properties such as osmotic pressure. Delta P . Delta T_b and Delta T_f . All these colligative properties are directly proportional to molality if solutions are dilute. The increases in colligative properties on addition of non-volatile solute is due to increases in number of solute particles. For different aqueous solutions of 0.1 N NaCI, 0.1 N urea, 0.1 N Na_2SO_4 and 0.1 N Na_3PO_4 solution at 27^@C , the correct statements are : 1. The order of osmotic pressure is NaCI = Na_2SO_4 = Na_3PO_4 = urea 2. pi = (Delta T_b)/k_b xx RT for urea solution 3. Addition of salt on ice increases its melting point 4. Addition of salt on ice bring in melting of ice earlier
