Colligative properties have many pracitical uses, some of them may be:
I: Melting of snow by slat
II: Desalination of sea water
III: Desalination of sea water
III: Determination of molar mass
IV: Determination of melting point and boiling point of solvent
Actual practical uses are :

Colligative properties have many practical uses , some of them may be : (P) melting of snow by salt (Q) desalination of sea water (R) determine of molar mass (S) determine of melting point and boiling point of solvent Actual practicle uses are :

(i) What is vinegar ? Give its uses. (ii) Why does carbon form compounds having low melting and boiling points ?

Identify the correct statements from the below about "Properties of Water". (I) High latent heat of vapourisation (II) Low latent heat of vapourisation (III) High melting and boiling points (IV) Universal solvent

Consider the following statements and arrange in order of true/false as given in the codes. S_1 : Vapour pressure is a colligative property. S_2 :Freezing point of a solution is always lower than of the pure solvent S_3 : Acetic acid undergoes association in benzene The molar mass of acetic acid, determined by elevation of boiling point is always higher than its normal molar mass. S_4 : Osomotic pressure measurements can be used for determination of molar mass of polymers.

n-Butylamine (I), diethylamine(II) andN,N -dimethylethyl amine (III) have the same molar mass. The increasing order of their boiling point is :
