What is the name of the compound with the formula CuSO3?
The Correct Answer and Explanation is :
The compound with the chemical formula CuSO₃ is Copper(I) sulfite or Cuprous sulfite.
Explanation:
1. Understanding the Chemical Formula (CuSO₃):
- The formula CuSO₃ consists of Cu (Copper), SO₃ (Sulfite ion).
- Sulfite (SO₃²⁻) is a polyatomic ion derived from sulfur and oxygen, carrying a -2 charge.
- Copper can exist in two common oxidation states: +1 (Cu⁺, Copper(I)) and +2 (Cu²⁺, Copper(II)).
- Since the sulfite ion has a -2 charge, and the formula shows only one copper atom, the charge of Cu must be +1 to balance the equation.
- Therefore, CuSO₃ represents Copper(I) sulfite (Cuprous sulfite), where Cu is in the +1 oxidation state.
2. Distinguishing Copper(I) and Copper(II) Sulfites:
- Copper(I) sulfite (CuSO₃): Less stable, tends to oxidize to Copper(II) over time.
- Copper(II) sulfite (CuSO₃·xH₂O): More commonly exists as a hydrated compound.
3. Properties of Copper(I) Sulfite:
- Appearance: Usually a white or pale-colored solid.
- Solubility: Poorly soluble in water.
- Stability: Unstable in air, readily oxidizing to Copper(II) compounds.
4. Uses and Applications:
- Not commonly used in industry due to its instability.
- Occasionally investigated in chemistry research.
Conclusion:
The correct name for CuSO₃ is Copper(I) sulfite (Cuprous sulfite), which is an uncommon, unstable compound.
