Which of the following solutions will exhibit highest boiling point?

Options

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

Answer

A

Explanation

`DeltaT = ixx K_(b) xx m`
`ixx m` of `Na_(2)SO_(4)` is highest, hence its boiling point will also be highest.
`{:(Na_(2)SO_(4),i xx m = 3 xx0.001 = 0.03),(KNO_(3),i xxm = 2 xx 0.01 =0.02),(Urea,i xx m =1 xx 0.015=0.015),(Glucose,ixxm = 1xx 0.015 =0.015):}`
