Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Colloids are classified by the physical state of the dispersed phase and of the dispersion medium; each combination has its own name.
(A) Cheese — This matches (III) Gel. A liquid dispersed in a solid (as in butter and jellies) is a gel.
(B) Cell fluids — This matches (IV) Sol. A solid dispersed in a liquid (as in paints) is a sol.
(C) Hair cream — This matches (I) Emulsions. A liquid dispersed in another liquid (as in milk) is an emulsion.
(D) Clouds — This matches (II) Aerosol. Liquid droplets dispersed in a gas (as in fog and mist) form an aerosol.
Shortcut: (A)-(III) appears only in Option (2).
