what is the correct IUPAC name for Cr2(SO4)3
The Correct Answer and Explanation is :
Correct IUPAC Name for Cr₂(SO₄)₃
The correct IUPAC name for Cr₂(SO₄)₃ is Chromium(III) sulfate.
Explanation:
- Understanding the Compound’s Composition
- The given chemical formula Cr₂(SO₄)₃ consists of two chromium (Cr) atoms and three sulfate (SO₄²⁻) ions.
- Chromium is a transition metal, and sulfate is a polyatomic anion.
- Determining the Oxidation State of Chromium
- The sulfate ion (SO₄²⁻) has a charge of -2.
- Since there are three sulfate ions, the total negative charge is:
[
3 \times (-2) = -6
] - To balance this charge, the two chromium atoms must have a total positive charge of +6.
- Therefore, each chromium atom has an oxidation state of +3.
- Naming the Compound
- In IUPAC nomenclature, transition metals require Roman numerals to indicate their oxidation state.
- Since chromium has a +3 oxidation state, it is written as Chromium(III).
- The polyatomic ion sulfate (SO₄²⁻) retains its name.
- Combining these, the correct IUPAC name is:
Chromium(III) sulfate.
Final Answer:
The correct IUPAC name for Cr₂(SO₄)₃ is Chromium(III) sulfate.
