Question

The values of van’t Hoff factors forKCl, 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

Answer 1

Answer: (B)

2, 2 and 3

Answer 2

$KCl\overset{\quad\quad}{\rightarrow}K^{+} + Cl^{-},thusi = 2$

$NaCl\overset{\quad\quad}{\rightarrow}Na^{+} + Cl^{-}thus,i = 2$

$K_{2}SO_{4}\overset{\quad\quad}{\rightarrow}2K^{+} + SO_{4}^{2 -}thus,i = 3$
