#Fe^(2+)#

Explanation:

A reducing reagent is always oxidized during a redox reaction.

During oxidation, an atom loses electrons or oxygen, and then increases its oxidation number.

From here, I see that iron(II) has been oxidized into iron(III), and is therefore the reducing reagent in this equation.
