Which of the following aqueous solution will exhibit highest boiling point?

Options

  1. A0.01 M Urea
  2. B0.01 M KNO ₃
  3. C0.01 M Na ₂ SO ₄
  4. D0.015 M C ₆ H ₁₂ O ₆

Correct answer

C. 0.01 M Na ₂ SO ₄

Step-by-step solution

T _ b = i ~K _ b ~m - Consider m M - K _ b same for all i M (1) 1 0.01=0.01 (2) 2 0.01=0.02 (3) 3 0.01=0.03 (4) 1 0.015=0.015 iM ~T _ b ~T _ b
