Na₂CO₃(aq) + CuSO₄(aq) → CuCO₃(s) + Na₂SO₄(aq)
Explanation:
* Na₂CO₃(aq) represents sodium carbonate dissolved in water (aqueous solution).
* CuSO₄(aq) represents copper sulfate dissolved in water.
* CuCO₃(s) represents copper carbonate, which is a solid precipitate (insoluble in water).
* Na₂SO₄(aq) represents sodium sulfate, which remains dissolved in water.
Observations:
When you mix the solutions, you will observe the following:
1. Formation of a blue-green precipitate: This precipitate is copper carbonate (CuCO₃).
2. Color change of the solution: The initial blue color of the copper sulfate solution will fade as the copper ions are removed from the solution by the formation of the precipitate.
Net ionic equation:
The net ionic equation shows only the species that are directly involved in the reaction:
Cu²⁺(aq) + CO₃²⁻(aq) → CuCO₃(s)
This equation highlights the formation of the solid copper carbonate from the copper ions (Cu²⁺) and carbonate ions (CO₃²⁻) in solution.
