WebApr 8, 2024 · Solution. Step 1: Separate the half-reactions. By searching for the reduction potential, one can find two separate reactions: Cu + (aq) + e − → Cu(s) and. Fe3 + (aq) + 3e − → Fe(s) The copper reaction has a higher potential and thus is being reduced. Iron is being oxidized so the half-reaction should be flipped. WebOxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2) where it is -1 and in compounds with fluorine (OF 2) where it is +2. Hydrogen has an oxidation …

Further the oxidation number of S increases from -2 in Cu 2 S to +4 in SO 2, therefore S is oxidised. Therefore, this reaction is a redox reaction.
The bonding in copper sulfides cannot be correctly described in terms of a simple oxidation state formalism because the Cu-S bonds are somewhat covalent rather than ionic in character, and have a high degree of delocalization resulting in complicated electronic band structures. Although many textbooks (e.g. ) give the mixed valence formula (Cu )2(Cu )(S )(S2) for CuS, X-ray photoelectron spectroscopic data give strong evidence that, in terms of the simple oxidation state formalism, a… WebApr 1, 2024 · Zn is oxidized (Oxidation number: 0 → +2); H + is reduced (Oxidation number: +1 → 0) Al is oxidized (Oxidation number: 0 → +3); Cu 2+ is reduced (+2 → 0) This is not a redox reaction because each element has the same oxidation number in both reactants and products: O= -2, H= +1, C= +4.
