Question

Which one of the following aqueous solutions will exhibit highest boiling point?

• A. 0.015 M urea
• B. 0.01 M KNO₃
• C. 0.01 M Na₂SO₄
• D. 0.015 M glucose

Answer 1

The correct option is C

0.01 M Na₂SO₄

Elevation in boiling point is a colligative property which depends upon the number of solute particles. Greater the number of solute particle in a solution higher the extent of elevation in boiling point.
