The values of van't Hoff factors for KCl...

The values of van't Hoff factors for KCl, NaCl and `K_(2)SO_(4)`, respectively, are ……

A

2, 2 and 2

B

2, 2 and 3

C

1, 1 and 2

D

1, 1 and 1

Text Solution

Verified by Experts

The correct Answer is:
B
Explanation : The values of van.t Hoff factor depend upon the extent of dissociation. KCl, NaCl and `K_(2)SO_(4)` are strong electrolytes. The extent or degree of dissociation would be greatest with `Na_(2)SO_(4)` as compared to that of KCl and NaCl.
