Question

Which of the following aqueous solution will exhibit highest boiling point?
(1) 0.015M C6H12O6
(2) 0.01M Urea
(3) 0.01M KNO3
(4) 0.01M Na2SO4

Accepted Answer

Correct Answer: D — 0.01M Na₂SO₄Step-by-step Solution:ΔTb = i × Kb × m. The higher the value of (i × m), the greater the boiling point elevation.Glucose (i=1): i×m = 1 × 0.015 = 0.015Urea (i=1): i×m = 1 × 0.01 = 0.010KNO₃ → K⁺ + NO₃⁻ (i=2): i×m = 2 × 0.01 = 0.020Na₂SO₄ → 2Na⁺ + SO₄²⁻ (i=3): i×m = 3 × 0.01 = 0.030 ← highest∴ 0.01M Na₂SO₄ has the highest boiling point.Key Concepts:Boiling point elevation: ΔTb = i × Kb × m (colligative property)van't Hoff factor (i): number of particles produced per formula unit in solution. Non-electrolyte: i=1; KNO₃: i=2; Na₂SO₄: i=3.Boiling point elevation is a colligative property — depends only on number of solute particles, not their nature.

Which of the following aqueous solution will exhibit highest boiling point? (1) 0.015M C6H12O6 (2) 0.01M Urea (3) 0.01M KNO3 (4) 0.01M Na2SO4
