Question

Match List I with List II:

Choose the correct answer from the options given below:

• A. A-II, B-I, C-IV, D-III
• B. A-III, B-I, C-IV, D-II
• C. A-III, B-II, C-I, D-IV
• D. A-II, B-IV, C-I, D-III

Hint:

In solutions, the phase of the solute and solvent determine the type of solution: - Solid in solid: Alloys. - Liquid in gas: Humidity. - Solid in gas: Smoke. - Liquid in solid: Amalgams.

Answer 1

The Correct Option is A

Let’s evaluate each example and match it with the correct type of solution:
- A. Humidity: Humidity refers to water vapor in the air, which is a liquid in gas solution.
Thus, A-II.
- B. Alloys: Alloys are mixtures of metals (solid in solid), such as brass or steel.
Thus, B-I.
- C. Amalgams: Amalgams are alloys of metals with mercury, where mercury is the liquid in a solid matrix.
Thus, C-IV.
- D. Smoke: Smoke is a solid in gas solution, consisting of solid particles dispersed in gas.
Thus, D-III.
Therefore, the correct matching is (1) A-II, B-I, C-IV, D-III.
