Iron exhibits +2 and +3 oxidation states. Which of the following statements about iron is incorrect?

1. Ferrous oxide is more basic in nature than ferric oxide.
2. Ferrous compounds are relatively more ionic than the corresponding ferric compounds.
3. Ferrous compounds are less volatile than the corresponding ferric compounds.
4. Ferrous compounds are more easily hydrolysed than the corresponding ferric compounds.

Correct answer: Ferrous compounds are more easily hydrolysed than the corresponding ferric compounds.

Solution

Ferrous compounds tend to be more easily hydrolyzed than ferric compounds due to their lower charge density, which allows them to interact more readily with water molecules, leading to hydrolysis.
