Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
The terms describe solutions by how much solute they hold, how many components they have, and how their osmotic pressures compare.
(A) Saturated solution. — This matches (III) A solution which contains the maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature. In a saturated solution the dissolved solute is in dynamic equilibrium with undissolved solute.
(B) Isotonic solutions — This matches (IV) The solutions having same osmotic pressure at a given temperature. No net osmosis takes place between isotonic solutions; 0.9% saline is isotonic with blood fluid.
(C) Binary solution — This matches (I) Solution having two components. “Binary” means two: one solute and one solvent.
(D) Hypertonic solution — This matches (II) A solution whose osmotic pressure is more than that of another. Cells placed in a hypertonic solution lose water and shrink.
Shortcut: (A)-(III) appears only in Option (4).
