Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(III), (B)-(II), (C)-(IV), (D)-(I)

The correct answer is Option (1) → (A)-(III), (B)-(II), (C)-(IV), (D)-(I)

Solutions are classified based on the physical states of solute and solvent. The state of the solvent decides the overall type of solution.

Explanation of each match

(A) Gas in liquid → (III) Aerated drinks

Aerated drinks contain carbon dioxide gas dissolved in water under pressure. Here, CO₂ is the solute (gas) and water is the solvent (liquid). Hence, this is a gas-in-liquid solution.

(B) Liquid in liquid → (II) Benzene in Toluene

Both benzene and toluene are liquids and are completely miscible with each other. When one liquid dissolves in another liquid, the solution is classified as liquid-in-liquid.

(C) Liquid in solid → (IV) Mercury in gold

Mercury forms an amalgam with gold. Mercury is a liquid and gold is a solid; the liquid dissolves into the solid matrix. This type of solution is called liquid-in-solid.

(D) Solid in solid → (I) Brass

Brass is an alloy of copper and zinc, both of which are solids. Alloys are examples of solid solutions where one solid dissolves in another solid.
