The electrolyte having the same value of Van't Hoff factor (i) as that of Al2(SO4)3 (if all are 100% ionized) is:
| 1. | K2SO4 | 2. | K3[Fe(CN)6] |
| 3. | Al(NO3)3 | 4. | K4[Fe(CN)6] |
| 1. | 0.05 M NaCl | 2. | 0.1 M KCl |
| 3. | 0.1 M MgSO4 | 4. | 0.1 M NaCl |
The van’t Hoff factor (i) for a dilute aqueous solution of a strong electrolyte barium hydroxide is:
1. 0
2. 1
