Solutions Question 38
Question: Which of the following has minimum freezing point [Pb. PMT 1999]
Options:
A) $ 0.1M $ $ K_2Cr_2O_7 $
B) 0.1 M $ NH_4Cl $
C) 0.1 M $ BaSO_4 $
D) 0.1 M $ Al_2{{(SO_4)}_3} $
Show Answer
Answer:
Correct Answer: D
Solution:
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 0.1M $ Al_2{{(SO_4)}_3} $ solution will have minimum freezing point.
