WebJan 23, 2024 · The first stage of the extended oxidation The acidified potassium manganate (VII) solution oxidizes the alkene by breaking the carbon-carbon double bond and replacing it with two carbon-oxygen double bonds. The products are known as carbonyl compounds because they contain the carbonyl group, C=O. WebThe (II) and (III) are the oxidation states of the iron in the two compounds: +2 and +3 respectively. That tells you that they contain Fe 2+ and Fe 3+ ions. This can also be extended to the negative ion. Iron (II) sulphate is FeSO 4. There is also a compound FeSO 3 with the old name of iron (II) sulphite.
