MCQ
Which of the following solution will exhibit highest boiling point
- A$0.01\,M\,Na_2SO_4$
- ✓$0.01\,M\,KNO_3$
- C$0.015\,M$ urea
- D$0.015\,M$ glucose
✓
Answer
Correct option: B.
$0.01\,M\,KNO_3$
b
$\pi=\mathrm{CRTi} \quad \mathrm{pH}=2$
$\pi=\mathrm{CRTi} \quad \mathrm{pH}=2$
$\mathrm{H}^{+}=10^{-2}=\mathrm{C} \alpha(\text { mono-basic acid })$
${\alpha=\frac{10^{-2}}{0.1}=0.1} $
${\mathrm{i}=1+\alpha(\mathrm{N}-1)}$
${\mathrm{i}=1+0.1(2-1)}$
${\mathrm{i}=1.1}$
${\pi=0.1 \times \mathrm{RT} \times 1.1} $
${\pi=0.11\,\, \mathrm{RT}}$
