MCQ
If for a sucrose solution elevation in boiling point is $0.1\,^o C$ then what will be the boiling point of $NaCl$ solution for same molal concentration .......... $^oC$
- A$0.1$
- ✓$0.2$
- C$0.08$
- D$0.01$
✓
Answer
Correct option: B.
$0.2$
b
(b)Elevation in a boiling point is a colligative property as it depends upon the number of particles.
(b)Elevation in a boiling point is a colligative property as it depends upon the number of particles.
$\Delta T_b \propto n$
For sucrose,$ n = 1, \Delta Tb = 0.1\,^o C$
For $ NaCl, n = 2, \Delta Tb = 0.2\,^o C$
