Question

Which of the following will have the highest boiling point at 1 atm pressure ?

• A. 0.1 M NaCl
• B. 0.1 M sucrose
• C. 01 M $BaCl_2$
• D. 0.1 M glucose

Answer 1

Answer: (C)

01 M $BaCl_2$

Answer 2

Using boiling point elevation formula, $\Delta T _{ b }= i \times K _{ b } \times$ molality Where $i$ is Van't Hoff factor. Highest Van't Hoff factor is for $BaCl _{2}$ which is $3 .$
