The equation CuSO4 + Na2S2O3 -> CuS2O3 + Na2SO4

Detailed information about the equation CuSO₄ + Na₂S₂O₃ -> CuS₂O₃ + Na₂SO₄:
The above chemical equation represents the reaction process between copper sulfate (CuSO₄) and sodium thiosulfate (Na₂S₂O₃), resulting in copper thiosulfate (CuS₂O₃) and sodium sulfate (Na₂SO₄).

Reaction conditions:
The reaction should be carried out in an acidic environment to promote the process effectively.

Reaction process:
CuSO₄ + Na₂S₂O₃ -> CuS₂O₃↓ + Na₂SO₄
Copper sulfate (II) (CuSO₄), in a blue solution, reacts with sodium thiosulfate (Na₂S₂O₃) in a colorless solution, forming copper thiosulfate (II) (CuS₂O₃) as a white precipitate and sodium sulfate (Na₂SO₄) in a colorless solution.

Occurring phenomena:
During the reaction process, the original blue solution of CuSO₄ gradually disappears and the white precipitate of CuS₂O₃ appears. At the same time, the solution becomes transparent due to the formation of Na₂SO₄.
