solution mixed with solution in 1:1 molar ratio gives the test of Fe2+ ion but solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of Cu2+ ion because:
| 1. | The former is an example of a basic compound, while the latter is an amphoteric compound |
| 2. | The former is an example of an amphoteric compound, while the latter is a basic compound |
| 3. | The former is an example of a double salt, while the latter is a coordination compound |
| 4. | The former is an example of a coordination compound, while the latter is a double salt |

The two coordination complexes, [Fe(CN)6]4– and [Fe(H2O)6]2+ are of different colors in dilute solutions, due to:
| 1. | Higher lattice energy value of [Fe(CN)6]4– as compared to [Fe(H2O)6]2+ |
| 2. | Higher CFSE value of [Fe(CN)6]4– as compared to [Fe(H2O)6]2+ |
| 3. | Lower CFSE value of [Fe(CN)6]4– as compared to [Fe(H2O)6]2+ |
| 4. | Lower lattice energy value of [Fe(CN)6]4– as compared to [Fe(H2O)6]2+ |
