Match List-I with List-II
|
List-I (Type of solution) |
List-II (Examples) |
|
(A) Gas in liquid |
(I) Brass |
|
(B) liquid in liquid |
(II) Benzene in Toluene |
|
(C) liquid in solid |
(III) Aerated drinks |
|
(D) solid in solid |
(IV) Mercury in gold |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
A solution is named by the physical states of the solute and the solvent, written as “solute in solvent”. The solvent decides the state of the solution.
(A) Gas in liquid — This matches (III) Aerated drinks. Carbon dioxide gas is dissolved in water under pressure; the gas escapes as bubbles when the bottle is opened and the pressure falls.
(B) liquid in liquid — This matches (II) Benzene in Toluene. Both components are liquids that mix completely; this pair forms a nearly ideal solution.
(C) liquid in solid — This matches (IV) Mercury in gold. Liquid mercury dissolves in solid gold to form an amalgam.
(D) solid in solid — This matches (I) Brass. Brass is an alloy in which zinc is dissolved in copper, both solids.
Shortcut: (D)-(I) appears only in Option (1).
The book table gives other examples of the same types: oxygen in water (gas in liquid), ethanol in water (liquid in liquid), an amalgam of mercury (liquid in solid) and copper in gold (solid in solid).
