MCQ
The vapour pressure is least for?
- Apure water
- B$0.1m$ aqueous urea
- CBoth $a$ and $b$
- ✓$0.3m$ aqueous urea
✓
Answer
Correct option: D.
$0.3m$ aqueous urea
Vapour pressure decreases as content of any impurity increases in solution.
$V.P$ will be least for $0.3m$ aq.urea.
$V.P$ will be least for $0.3m$ aq.urea.
