Which of the following aqueous solution should have highest boiling...

Which of the following aqueous solution should have highest boiling point?

Options

  1. A1.0 M NaOH
  2. B1.0 M Na2SO4\mathrm{Na}_2 \mathrm{SO}_4
  3. C1.0M1.0 \mathrm{M} NH4NO3{NH}_4 \mathrm{NO}_3
  4. D1.0 M KNO3\mathrm{KNO}_3

Correct answer

B. 1.0 M Na2SO4\mathrm{Na}_2 \mathrm{SO}_4

Step-by-step solution

More be value of van't Hoff factor (i), more be the boiling point. ∵i\because i is maximum for Na2SO4(=3)\mathrm{Na}_2 \mathrm{SO}_4(=3) ∴\therefore It has maximum b.p.
