Van't Hoff factor i 1 for a solute indicates

Question

Van't Hoff factor i > 1 for a solute indicates

Accepted Answer

C. {'text': 'Dissociation of the solute into ions', 'label': 'C'}

1. Van't Hoff factor i is the ratio of observed to calculated colligative effect.
2. i > 1 implies more particles than the formula suggests: dissociation.
3. Example: NaCl in water gives i ≈ 2 (near complete dissociation into Na⁺ and Cl⁻).
4. Dimerisation gives i < 1; ideal non-electrolyte gives i = 1.
