(a)
Interpretation:
Whether the reaction is an oxidation or a reduction when Fe3+ is converted into Fe2+ needs to be determined.
Concept introduction:
In the oxidation process, electrons are lost in a reaction from an atom or an ion. In an oxidation reaction, the oxidation state of the respective atom increases. It is also termed as addition of oxygen atom in a molecule. On the other hand, reduction is termed as gain of electrons or hydrogen atoms. It is also termed as loss of oxygen atoms. The oxidation state of the atom or ion decreases during reduction.
(b)
Interpretation:
Whether Fe3+ is an oxidizing agent or a reducing agent needs to be determined.
