List-I (Types of solutions) |
List-II (Examples) |
|
(A) Gas in Gas solution |
(I) Oxygen dissolved in water |
|
(B) Gas in Liquid solution |
(II) Copper dissolved in gold |
|
(C) Liquid in Solid solution |
(III) Mixture of oxygen and nitrogen gases |
|
(D) Solid in Solid solution |
(IV) Amalgam of mercury with sodium |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
A solution is named by the physical state of its solute and of its solvent, the component present in the larger amount. The state of the solution is that of the solvent.
(A) Gas in Gas solution — This matches (III) Mixture of oxygen and nitrogen gases. Both components are gases, as in air.
(B) Gas in Liquid solution — This matches (I) Oxygen dissolved in water. The gas oxygen is the solute and liquid water the solvent; this dissolved oxygen keeps aquatic life going.
(C) Liquid in Solid solution — This matches (IV) Amalgam of mercury with sodium. Liquid mercury is dissolved in solid sodium.
(D) Solid in Solid solution — This matches (II) Copper dissolved in gold. Such alloys are solid solutions of one metal in another.
Shortcut: (A)-(III) and (B)-(I) are in Options (1) and (3); mercury is a liquid, so the amalgam is (C), which leaves Option (3).
