Question

Iron has low Standard electrode potential in +3 oxidation state value because ?​

Answer 1

Answer:

The oxidation state of an element is related to the number of electrons that an atom . Almost all of the transition metals have multiple potential oxidation states. This is because copper has 9 d-electrons, which would produce 4 paired  Other possible oxidation states for iron includes: +5, +4, +3, and +2.
