Match List I with List II
| List I | List II |
| (A) Liquid in solid | (I) Hydrated salt |
| (B) Gas in solid | (II) Camphor in nitrogen gas |
| (C) Gas in liquid | (III) Aerated drinks |
| (D) Solid in gas | (IV) Dissolved gases in minerals |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(I), (B)-(IV), (C)-(III), (D)-(II)
(A) Liquid in solid — This matches (I) Hydrated salt. The solute, water (a liquid), is held inside the crystal of the solid salt. The book’s example of this type is the amalgam of mercury with sodium.
(B) Gas in solid — This matches (IV) Dissolved gases in minerals. The gas is the solute and the solid mineral is the solvent, as in the book’s example, a solution of hydrogen in palladium.
(C) Gas in liquid — This matches (III) Aerated drinks. Carbon dioxide (gas) is dissolved in water (liquid) under pressure, like the book’s example, oxygen dissolved in water.
(D) Solid in gas — This matches (II) Camphor in nitrogen gas. Camphor (solid) sublimes and its vapour mixes with nitrogen, which is the solvent.
