The values of Van A. 2, 2 and 2

B. 2, 2 and 3

C. 1, 1 and 2

D. 1, 1 and 1

The van’t Hoff factor is:

i = Total number of ions after dissociation/association/Total number of ions before dissociation/association.

Thus, for KCl, van’t Hoff factor = 2,

for NaCl van’t Hoff factor is 2 and

for K₂SO₄ van’t Hoff factor is 3.

Thus, Option 2 is the correct answer.
