Mention three specific conditions necessary for the determination of correct molar mass of a solute by studying colligative properties of its solution.

Which colligative property is most suitable for the determination of molecular masses of polymer?

Derive the relation between molar mass of solute and elevation of boiling point

Derive the relation between molar mass of solute and elevation of boiling point

In which of the following pairs of solutions will the values of the colligative properties be the same?

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

Mention the conditions for determination of biodiversity Hot-spot. Describe any three kinds of population interaction with example.

Which one of the statements given below concerning properties of solution, describes a colligative effect ?

Why are the magnitudes of colligative properties of colloidal solutions lower than those of true solutions?
