Copper carbonate + Sodium sulfate → Copper carbonate (green precipitate) + Sodium carbonate
Here's a more detailed explanation:
* Copper carbonate (CuCO3) is a green, solid compound.
* Sodium sulfate (Na2SO4) is a colorless, soluble salt.
* Copper carbonate (CuCO3) is the green precipitate that forms.
* Sodium carbonate (Na2CO3) is also soluble and remains in solution.
The reaction actually involves a double displacement reaction where the copper and sodium ions exchange partners. However, since copper carbonate is insoluble, it precipitates out of the solution, giving the characteristic green color.
