Question

(2) Which of the following will have maximum depression in freezing point? (a) 0.5 M LiSO4 (b) 1 M KC1 (c) 0.5 M Al2(SO4)3 (d) 0.5 M BaCl2 ​

Answer 1

Answer:

here is your answer

option c 0.5 M Al2

Answer 2

Answer:

Correct option is

C

0.5 M Al

2

(SO

4

)

3

T

f

=iK

f

m

Depression in freezing point will be maximum for the compound having maximum van't Hoff factor i which is maximum for Al

2

(SO

4

)

3

which furnishes 5 ions in the solution, therefore i=5 hence, it will have maximum depression in freezing point in case of the same concentration.

Here, in case of Al

2

SO

4

and NaCl, Al

2

SO

4

have higher i×C value.
