Q. Which of the following aqueous solution will exhibit highest boiling point?
A) 0.01 M Urea
B) 0.01 M KNO$_3$
C) 0.01 M Na$_2$SO$_4$
D) 0.015 M C$_6$H$_{12}$O$_6$
Explanation
[Solution by Claude - not from source] $\Delta T_b\propto iC$: urea $0.01$; $KNO_3$ $0.02$; $Na_2SO_4$ $0.03$; glucose $0.015$. $Na_2SO_4$ is highest. Answer (3).
