4.4: Oxidation-Reduction Reactions - Chemistry LibreTexts

23/06/2021& 0183;& 32;Fractional oxidation states are allowed because oxidation states are a somewhat arbitrary way of keeping track of electrons. In fact, Fe 3 O 4 can be viewed as having two Fe 3 ions and one Fe 2 ion per formula unit, giving a net positive charge of 8 per formula unit. Fe 3 O 4 is a magnetic iron ore commonly called magnetite. In ancient times, magnetite was known as lodestone because it

Redox - Wikipedia

Redox reduction–oxidation, pronunciation: / ˈ r ɛ d ɒ k s / RED-oks or / ˈ r iː d ɒ k s / REE-doks is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species the reducing agent undergoing oxidation losing electrons while

Other oxidation reduction reactions

Oxidation: When a species loses electrons and becomes more positively charged. Reduction: When a species gains electrons and becomes more negatively charged. The following is an oxidation/reduction reaction redox reaction. Iron is Fe and Fe 2 O 3 is red rust. O 2 is oxygen. You might think that water is required for this process but it is not, it merely speeds it up. Notice that the iron is

Is iron in the brown ring compound in a 1 oxidation state

In this compound, the nitrosyl ligand is positively charged, and iron is in a $ 1$ oxidation state. Now, iron has stable oxidation states 2 and 3. Nitrosyl, as a ligand, comes in many flavours, of which a negatively charged nitrosyl is one. I see no reason why the iron doesn't spontaneously oxidise to 3 and reduce the $\ce NO $ to −1 to gain stability. But I don't know how to analyse this
