Answer 2

Reaction Equations:

To represent the given transformations, we can write the following reaction equations:

1. FeCl3 <-- Fe --> FeSO4 --> Fe(OH)2 --> Fe(OH)3

Oxidation-Reduction Reaction:

Let's consider reaction #1 as an oxidation-reduction reaction. In this reaction, iron (Fe) undergoes changes in its oxidation state.

The oxidation state of iron in FeCl3 is +3, while in FeSO4, it is +2. Therefore, iron is reduced from an oxidation state of +3 to +2.

The reaction can be represented as an ionic equation:

FeCl3 + 3e- --> Fe

Ionic Equation for Reaction #3:

To write the ionic equation for reaction #3, which is the transformation of Fe(OH)2 to Fe(OH)3, we need to consider the dissociation of the compounds involved.

Fe(OH)2 dissociates into Fe2+ and 2OH- ions, while Fe(OH)3 dissociates into Fe3+ and 3OH- ions.

The ionic equation for the reaction can be written as:

Fe(OH)2 + OH- --> Fe(OH)3

Please note that this equation represents the transformation of Fe(OH)2 to Fe(OH)3, but it does not capture the complete reaction pathway from FeSO4 to Fe(OH)3. If you need a more detailed explanation of the reaction pathway, please let me know.
