Properties Of Solution

Mole fractions are typically used to calculate which properties for solutions containing non-volatile solutes ? (P) Freezing point depression (Q) Osmotic pressure (R) Vapour pressure

Colligative properties i.e., the properties of solution which depend upon the particles present in solution are osmotic pressure, depression in freezing point, elevation in boiling point and relative lowering of vapour pressure. Experimental values of colligative properties for electrolytes are always higher than those obtained theoreticallu. The ratio of experimental colligative properties to theoretical colligative properties is called as van't Hoff factor (i). What is observed molar mass of weak acid in soluton in above equation?

Colligative properties of solution depend upon the number of particles present in solution. Experimental values colligative properties for electrolytes are always higher than these obtained theoretically because electrolyte dissociates to furnish more ions in solution. The ration of experimental values to theoretical values is called as van't Hoff factor (i) . For 1M solution of a weak acid HA , the dissociation constant K in terms of van't Hoff factor:

Colligative properties of solution depend upon the number of particles present in solution. Experimental values colligative properties for electrolytes are always higher than these obtained theoretically because electrolyte dissociates to furnish more ions in solution. The ration of experimental values to theoretical values is called as van't Hoff factor (i) . The correct order of freezing point for the following, each are 1 molal solutions in water and take alpha = 1 : (i) Urea , (ii) NaCl (iii) Na_(3)PO_(4) , (iv) Na_(2)SO_(4)
