Question
What is the IUPAC name for Fe2O3? iron (III) oxide iron oxide iron (II) trioxide iron (II) oxide iron trioxide
Solution
The IUPAC name for Fe2O3 is iron (III) oxide.
Here's the step by step explanation:
-
The formula Fe2O3 is composed of two elements: iron (Fe) and oxygen (O).
-
The subscript '2' after Fe indicates that there are two atoms of iron.
-
The subscript '3' after O indicates that there are three atoms of oxygen.
-
In IUPAC nomenclature, the oxidation state of the metal ion is represented in Roman numerals within parentheses after the name of the metal. In this case, iron has an oxidation state of +3 (since oxygen has an oxidation state of -2 and the compound must be electrically neutral).
-
Therefore, the IUPAC name for Fe2O3 is iron (III) oxide.
