Redox reaction-naming the substance reduced

[QUOTE="PWiz, post: 4960230, member: 536763"] The oxidation state of an element in a compound is given for one of its atoms, so you don't have to multiply it by the number of atoms actually present in the compound. For example, Na2O and Al2O3 have different number of oxygen atoms in each compound, but oxygen has the same oxidation number(-2) in both cases, even though there are 3 oxygen atoms in aluminum oxide(its oxidation state is NOT -2 x 3). With this logic, try working out the oxidation numbers for each atom in the original question on both sides of the equation. [/QUOTE]
