Solutions

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

A.0.01 M urea
B.0.01 M $KN O_{3}$
C.0.01 M $N a_{2} S O_{4}$ ✓
D.0.015 M $C_{6} H_{12} O_{6}$

Solution

Boiling-point elevation depends on the total particle concentration $i C$ . Urea: $0.01$ . $KN O_{3}$ : $2 \times 0.01 = 0.02$ . $N a_{2} S O_{4}$ : $3 \times 0.01 = 0.03$ . Glucose: $0.015$ . $N a_{2} S O_{4}$ boils highest.
