Osmotic pressure is a colligative property and it is proportional to the molarity of solution. What is osmotic pressure ?

Osmotic pressure is a colligative property What is osmotic pressure ?

Relative lowering of vapour pressure, elevation of boiling point, depression of freezing point and osmotic pressure are important colligative properties of dilute solutions. Relative lowering of vapour pressure of an aqueous dilute solution of glucose is 0.018 What is the mole fraction of glucose in the solution ?

Two solutions of glucose have osmotic pressures 1.5 and 2.5 atm. 1 litre of first solution is mixed with 2 litre of second solution. The osmotic pressure of the resultant solution will be:

Show that (i) elevation in boiling point is a colligative property (ii) depression in freezing point is a colligative property and (iii) osmotic pressure is a colligative property?

Osmotic pressure is measured quickiy and accurately by

Elevation of boiling point is a colligative property:Elevation of boiling point (DeltaT_b) is directly proportional to molality (m) of solution. Thus DeltaT_b = K_bm, K_b is called the molal elevation constant. From,the above relation derivean expression to obtain molar mass of the solute.
