Or: The iron in the iron oxide is reduced from +3 oxidation state to zero while the carbon is oxidised from an oxidation state of +2 to +4. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). The IR s Catalysis on Zeolites of e’s lost or gained by the element during its change from free state to that compound. +3 oxidation state is rare but does exist. For this to be so, Sn must be 2+ in charge, giving a net -1 charge. It donates these electrons to be a stable ion. Oxidation number of K is +1. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component.
