10 Solution Part 10 Colligative Properties Depresion in Freezing Point 12th Iit Jee Neet Pgt 1

Assertion : Depression of freezing point is a colligative property Reason : The depression of freezing point for a solution is directly proportional to the molality of the solution.

For 0.1M solution ,the colligative property will follow the order

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). If equal volume of 0.01 M Ma OH is added in the solution of above weak acid solution then what will be new observed osmotic pressure at same temperature? Neglect the hydrolysis, dissociation of water and any volume concentration or expansion. Assume 10% dissociation of salt formed.

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?

Explain giving examples the term 'colligative molality'. Why do we sometimes get abnormal molecular masses of the substances using colligative properties of the solution? The freezing point depression of 0.1 molal solution of benzoic acid in benzene is 0.526K . For benzene K_(f) is 5.12K kg "mol"^(-1) . Calculate the value of van't Hoff factor for benzoic acid in benzene. What conclusion can you draw about the molecular state of benzoic acid in benzene?

Colligative properties i.e., the properties of solution which depends upon the number pf aprticles present in solution are osmotic pressure, depression in freezing point, elevation in boiling point and lowering in vapour pressure. Experimental values of colligative properties for electroetically because electrolytes dissociates to furnish more ions in solution. On the other hand experimentally obtained values of colligative properties for associating nature of solute ate lower than those obtained theoretically. The ratio of experimantal colligative properties to theoretical colligative properties is called as van't Hoff factor (i) . van't Hoff coefficient 'g' for 100% dissociated NaCl solution is:
