Question
Colligative properties have many practical uses, some of them may be :
I : Melting of snow by salt
II : Desalination of sea water
III : Determination of molar mass
IV : Determination of melting point and boiling point of solvent
Actual practical uses are :
I : Melting of snow by salt
II : Desalination of sea water
III : Determination of molar mass
IV : Determination of melting point and boiling point of solvent
Actual practical uses are :
Options
A.I, II
B.III, IV
C.I, II, III
D.II, III, IV
Solution
I. Melting of snow by salt : Depression in freezing point
II. Desalination of sea water : Reverse osmosis
III. Osmosis is used to determine the molar mass.
