The values of Van’t Hoff factors for KCl, NaCl and , respectively, are
_____________.
(i) 2, 2 and 2
(ii) 2, 2 and 3
(iii) 1, 1 and 2
(iv) 1, 1 and 1
The answer is the option (ii). While KCl and NaCl ionize to give 2 ions, gives 3 ions. So, van’t Hoff factors for KCl, NaCl and K2SO4 are 2,2 and 3 respectively
