Question
The values of Van’t Hoff factors for KCl, NaCl and K2SO4, respectively, are ______.
Options
2, 2 and 2
2, 2 and 3
1, 1 and 2
1, 1 and 1
Solution
The values of Van’t Hoff factors for KCl, NaCl and K2SO4, respectively, are 2, 2 and 3.
Explanation:
\[\ce{KCl (K+ + Cl)}\] and \[\ce{NaCl (Na+ + Cl)}\] ionize to give 2 ions and \[\ce{K2SO4(2K+ + SO^{-}4)}\] ionizes to give 3 ions thus, van’t Hoff factors for \[\ce{KCl}\], \[\ce{NaCl}\] and \[\ce{K2SO4}\] are 2, 2 and 3 respectively.
