List-I (Types of solutions) |
List-II (Examples) |
|
(A) Gas in Gas solution |
(III) Mixture of oxygen and nitrogen gases |
|
(B) Gas in Liquid solution |
(I) Oxygen dissolved in water |
|
(C) Liquid in Solid solution |
(IV) Amalgam of mercury with sodium |
|
(D) Solid in Solid solution |
(II) Copper dissolved in gold |
(A) Gas in Gas solution: This occurs when one gas is mixed with another. Since all gases mix uniformly, air is the most common example.
- Matches with (III): Mixture of oxygen and nitrogen gases.
(B) Gas in Liquid solution: This occurs when a gas is dissolved in a liquid solvent.
- Matches with (I): Oxygen dissolved in water (essential for aquatic life).
(C) Liquid in Solid solution: This is a unique case where a liquid (solute) is dispersed within a solid (solvent).
- Matches with (IV): Amalgam of mercury with sodium. Mercury is a liquid at room temperature, while sodium is solid.
(D) Solid in Solid solution: These are typically alloys where one metal is mixed into another in a molten state and then cooled.
- Matches with (II): Copper dissolved in gold (used to make jewelry harder).
