Why the freezing point of pure solvent is more than that of solution. Draw the curve showing the fact stated above.

Why the boiling point of salt water is higher than pure water?

Why is the electrical conductivity of phosphorus-doped silicon is more than that of pure silicon?

What is the freezing point of solution containing 3g of a non-volatile solute in 20g of water. Freezing point of pure water is 273K, K_(f) of water = 1.86 Kkg/mol. Molar mass of solute is 300 g/mol. T^(@)-T=K_(f)m

Why is iodine more soluble in KI solution than in water ?

Calculate the freezing point of a solution of a non-volatile solute in a unknown solvent of molar mass 30 g/mol having mole fraction of solvent equal to 0.8. Given that latent heat of fusion of solid solvent = 2.7 kcal mol(-1)k^(-1) , freezing point of solvent = 27^@C and R = 2 cal mol^(-1) k^(-1)

A very small amount of a nonvolatile solute (that does not dissociate) is dissolved in 56.8 cm^3 of benzene (density 0.889 g cm^-3 ). At room temperature, vapour pressure of this solution is 98.88 mm Hg while that of benzene is 100 mm Hg. Find the molality of this solution. If the freezing temperature of this solution is 0.73 degree lower than that of benzene, what is the value of molar freezing point depression constant of benzene ?

Show graphically how the vapour pressures of a solvent and a solution of a non-volatile solute in it change with temperature. Show on the graph boiling point of the solvent and the solution. Which is higher and why?

Depression in freezing point is __________pronounced if camphor is used as a solvent in place of water for same amount of solute and solvent.

This question has statement I and II. Of the four choices given after the statements, choose the one that best describes the two statements. Statement - I : If a liquid solute more volatile than the solvent is added to the solvent, the vapour pressure of the solution is greater than vapour pressure of pure solvent. Statement -II : Vapour pressure of solution is equal to vapour pressure of solvent.

Why the electrical conductivity of the solution produced by adding little sulphuric acid into pure water is more than the electrical conductivity of pure water?
