Out of the following $1.0\text{ M}$ aqueous solutions, which one will show the largest freezing point depression?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → $\text{Al}_2(\text{SO}_4)_3$ ##
Because it generatees higher number of ions after dissociation.
$\text{Al}_2(\text{SO}_4)_3 \rightarrow 2\text{Al}^{3+} + 3\text{SO}_4^{2-}$
$2 + 3 = 5$
