solution and colligative properties notes pdf

The pressure exerted by vapor at this stage is called as Vapor pressure Vapour pressure of a liquid, increases with the increase of temperature Note If the boiling 

Note Best method to express concentration as it is temperature independent 6) Normality (N) It is defined as the no of gram equivalents of solute dissolved in 1  

Note we had mole fraction in gases, but the same idea applies to solutions Since colligative properties depend on the ratio of solvent to solute molecules,

Note that the moloaity calculation is similar to a molarity calculation except that we divide by the mass of the solvent in kg rather than the liters of solution m =

Calculate the concentration of a solution in terms of molarity, molality, mole fraction, percent composition, and Use colligative properties of solutions to calculate molar masses of solutes ➢ Explain the Note The van't Hoff factor can also be 

On adding 24 g of water to the solution, the resulting solution (80 + 24 = 104 g) has vapour pressure of 3563 mm Hg at 298 K 2 2 p 3563 20 18 346 104 M M
