MCQ
Which of the following has lowest freezing point
- A$0.1\,M$ aqueous solution of glucose
- ✓$0.1\,M$ aqueous solution of $NaCl$
- C$0.1M$ aqueous solution of $ZnS{O_4}$
- D$0.1\,M$ aqueous solution of urea
✓
Answer
Correct option: B.
$0.1\,M$ aqueous solution of $NaCl$
b
(b) $NaCl $ gives maximum ion hence it shows lowest freezing point
(b) $NaCl $ gives maximum ion hence it shows lowest freezing point
