What is the IUPAC name of Fe(NO3)2? (You must spe Points possible: This Is attempt of 1_ Submit 1
The Correct Answer and Explanation is:
The IUPAC name of Fe(NO3)2 is Iron(II) nitrate.
Explanation:
- Fe represents iron (a transition metal), and it is in the +2 oxidation state because it is paired with two nitrate ions (NO3-) which each have a -1 charge. The oxidation state of iron can be deduced based on the fact that the total charge of the compound is neutral.
- The (II) in the name indicates the oxidation state of iron in this compound. The oxidation state of iron in Fe(NO3)2 is +2, and this is why we use Iron(II).
- Nitrate is the name for the NO3 ion, a common polyatomic ion. The term “nitrate” is used when referring to salts derived from nitric acid (HNO3).
Therefore, when combined, the name becomes Iron(II) nitrate. This name adheres to the IUPAC nomenclature system, where:
- The metal (iron) is named first.
- The oxidation state of the metal is given in parentheses using Roman numerals.
- The anion (nitrate, in this case) is named second.
Additional Notes:
Iron(II) nitrate is a salt formed by the reaction between iron(II) and nitric acid. It is commonly used in laboratory settings and may be encountered in both solid and aqueous forms. When iron is in the +2 oxidation state, it forms a variety of compounds, but the nitrate form is one of the most well-known.
