Iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction
natulia [17]

iron has two oxidation states +2 and + 3 there are two possible equations for the redox reaction - comparatively speaking, ferrous compounds are easier to hydrolyze than their ferric counterparts.

<h3>What is Redox reaction ?</h3>

Compared to ferric oxide, ferrous oxide is more basic in makeup. Comparatively speaking, ferrous compounds are more ionic than their ferric counterparts. Due to the fact that ferrous compounds are more ionic than their corresponding ferric ones, they are less volatile.

The greater positive charge of ferric compounds, however, makes them easier to hydrolyze than the comparable ferrous ones.

The quantity, kind, and distances of the iron atom's neighbors all contribute to their stability. Because each Fe atom is only weakly linked together by three electrons, which makes them susceptible to being dragged away by strong electronegative neighbors like oxygen, both types of ions are stable.
