Match solution in List-I with nature of solute and solvent List-II

Choose the correct answer from the options given below:

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

The correct answer is Option (4) → (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Solutions can exist in solid, liquid, or gaseous phases depending on the physical state of the solute and the solvent.

Option A: Amalgam of mercury in sodium

Amalgam is formed when a liquid metal (Hg) dissolves in solid metal (Na).

So this is liquid in solid.

(A) → (III)

Option B: An alloy

Alloy is a solid solution of one metal in another.

Example: Copper in gold

(B) → (IV)

Option C: Saturated solution of KCI

KCl is solid and dissolves in water (liquid).

So this is solid in liquid.

(C) → (I)

Option D: Chloroform in nitrogen gas

Chloroform vapour dissolves in nitrogen gas.

So this is liquid in gas.
