Cu(NO₃)₂ (aq) + Na₂CO₃ (aq) → CuCO₃ (s) + 2 NaNO₃ (aq)
Explanation:
* Reactants:
* Copper nitrate (Cu(NO₃)₂) is a blue, soluble ionic compound.
* Sodium carbonate (Na₂CO₃) is a white, soluble ionic compound.
* Products:
* Copper carbonate (CuCO₃) is a blue-green, insoluble ionic compound. It precipitates out of the solution as a solid.
* Sodium nitrate (NaNO₃) is a colorless, soluble ionic compound that remains in the solution.
Key Points:
* The reaction produces a precipitate (CuCO₃), which is a solid that forms and settles out of the solution.
* The reaction is driven by the formation of this insoluble precipitate.
* The (aq) symbol indicates that the compound is dissolved in water (aqueous solution).
* The (s) symbol indicates a solid compound.
You can observe this reaction visually. When you mix solutions of copper nitrate and sodium carbonate, you'll see a blue-green solid (copper carbonate) forming in the solution.
