Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Concentration terms tell how much solute is present per amount of solution or solvent; colligative properties depend only on the number of solute particles; real solutions deviate from Raoult’s law.
(A) Molarity — This matches (III) Number of moles of solute/litre of solution. M = moles of solute / volume of solution in L.
(B) Molality — This matches (I) Number of moles of solute/kilogram of solvent. m = moles of solute / mass of solvent in kg; it does not change with temperature.
(C) Colligative property — This matches (II) Osmotic pressure. π = CRT depends only on the number of solute particles; relative lowering of vapour pressure, elevation of boiling point and depression of freezing point are the others.
(D) Non-ideal solution — This matches (IV) Deviation from Raoult’s Law. A non-ideal solution does not obey Raoult’s law over the whole range of concentration; it shows positive or negative deviation.
Shortcut: (A)-(III) leaves Options (1) and (2); (C)-(II) then leaves only Option (2).
