Web3) In naming some ionic compounds, when are Roman Numerals needed? Give an example. The Roman numeral denotes the charge and the oxidation state of the transition metal ion. For example, iron can form two common ions, Fe2+ and Fe3+. To distinguish the difference, Fe2+ would be named iron (II) and Fe3+ would be named iron (III). WebThe key difference between iron II chloride and iron III chloride is that the Fe atom in iron(II) chloride chemical compound has +2 oxidation state whereas the Fe atom in iron(III) chloride compound has a +3 oxidation state. How do you identify Fe2+ and Fe3+ in a solution? Fe2+ has a pale green colour and turns violet when added to water. phenumb sandaler noelle
