Match the LIST-I with LIST-II
| LIST-I Type of solution | LIST-II Example |
| A. Solid solute in solid solvent | I. Glucose dissolved in water |
| B. Gaseous solute in solid solvent | II. Copper dissolved in gold |
| C. Liquid solute in solid solvent | III. Amalgam of mercury with sodium |
| D. Solid solute in liquid solvent | IV. Solution of hydrogen in palladium |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-II, B-IV, C-III, D-I
A solution is named by the physical state of the solute and that of the solvent. With three states for each there are nine types, and the solvent decides the state of the solution.
A. Solid solute in solid solvent — This matches II. Copper dissolved in gold. Both components are solids; alloys such as this are solid solutions.
B. Gaseous solute in solid solvent — This matches IV. Solution of hydrogen in palladium. Palladium absorbs large volumes of hydrogen gas into its metal lattice.
C. Liquid solute in solid solvent — This matches III. Amalgam of mercury with sodium. Liquid mercury is dissolved in solid sodium.
D. Solid solute in liquid solvent — This matches I. Glucose dissolved in water. Solid glucose is the solute and liquid water is the solvent.
Shortcut: The pair A–II appears in Options (1) and (2), and B–IV then leaves only Option (2).
