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

Options

A. 0.015 M urea
B. 0.01 M `KNO_(3)`
C. 0.01 M `Na_(2)SO_(4)`
D. 0.015 M glucose

Answer

C

Explanation

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.
`Na_(2)SO_(4)rarr2Na^(+)+SO_(4)^(2-)`
