a compound is made up of iron and oxygen, only. the ratio of iron ions to oxide ions is 2:3 in this compound. the iupac name for this compound is?
iron(III)oxide
I would call it iron(II) oxide.
To determine the IUPAC name for a compound made up of iron and oxygen, we first need to know the oxidation states of each element in the compound.
For iron (Fe), there are two common oxidation states: +2 and +3. Oxygen (O) typically has an oxidation state of -2.
Given the information that the ratio of iron ions (Fe) to oxide ions (O) is 2:3 in the compound, it suggests that iron has an oxidation state of +3. This is because the ratio of iron ions to oxide ions should reflect the charges of the ions involved. In this case, the 2:3 ratio indicates that iron forms Fe3+ ions and oxygen forms O2- ions.
With the knowledge that iron has an oxidation state of +3 and oxygen has an oxidation state of -2, we can use the IUPAC naming conventions to determine the compound's name.
The compound formed by iron (III) ions and oxide ions is named as iron (III) oxide. The IUPAC name for this compound is Ferric Oxide.
Therefore, the IUPAC name for the compound made up of iron and oxygen, with a ratio of iron ions to oxide ions being 2:3, is Ferric Oxide.
