When `Na_(2)CO_(3)` is added to an aqueous solution of `CuSO_(4)`

Options

A. `CuCO_(3)` is precipitated
B. Copper hydroxide is precipitated
C. Basic copper carbonate is percipitated
D. No reaction takes place

Answer

To solve the problem of what happens when sodium carbonate (Na₂CO₃) is added to an aqueous solution of copper sulfate (CuSO₄), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- We have sodium carbonate (Na₂CO₃) and copper sulfate (CuSO₄) as our reactants.

2. **Write the Chemical Equation**:
- When Na₂CO₃ reacts with CuSO₄, the reaction can be represented as:
\[ \text{Na}_2\text{CO}_3 (aq) + \text{CuSO}_4 (aq) \rightarrow \text{CuCO}_3 (s) + \text{Na}_2\text{SO}_4 (aq) \]

3. **Identify the Products**:
- The products of this reaction are copper carbonate (CuCO₃) and sodium sulfate (Na₂SO₄).

4. **Determine the State of the Products**:
- Copper carbonate (CuCO₃) is insoluble in water, which means it will precipitate out of the solution as a solid. Sodium sulfate (Na₂SO₄) remains in the aqueous state.

5. **Conclusion**:
- The key point here is that when Na₂CO₃ is added to CuSO₄, copper carbonate (CuCO₃) precipitates out of the solution.

### Final Answer:
The correct product formed when Na₂CO₃ is added to an aqueous solution of CuSO₄ is copper carbonate (CuCO₃), which precipitates out as a solid.
