MCQ
Which of the following has minimum freezing point
- A$0.1\,M$ ${K_2}C{r_2}{O_7}$
- B$0.1 \,M$ $N{H_4}Cl$
- C$0.1\,M $ $BaS{O_4}$
- ✓$0.1\,M $ $A{l_2}{(S{O_4})_3}$
✓
Answer
Correct option: D.
$0.1\,M $ $A{l_2}{(S{O_4})_3}$
d
(d) We know that lowering of freezing point is a colligative property which is directly proportional to the number of particles formed by one mole of compound therefore $0.1\,M$ $A{l_2}{(S{O_4})_3}$ solution will have minimum freezing point.
