Step-by-step explanation:
Na2CO3 (sodium carbonate) can indeed dissolve copper (Cu) in water, but the reaction does not result in the formation of CuCO3 (copper carbonate). Instead, the reaction between Na2CO3 and Cu proceeds as follows:
2Na2CO3 + Cu → CuCO3 + Na2O + CO2
In this reaction, sodium carbonate reacts with copper to form copper carbonate (CuCO3), sodium oxide (Na2O), and carbon dioxide (CO2). While CuCO3 is insoluble in water, it can initially form as a solid precipitate when the reaction occurs. However, due to the presence of sodium oxide and carbon dioxide, CuCO3 reacts further to form soluble copper-containing species, such as copper hydroxide (Cu(OH)2) or copper bicarbonate (Cu(HCO3)2).
The soluble copper species formed in the reaction can then dissolve in water, allowing the overall dissolution of copper when Na2CO3 is present. It is important to note that the exact products and their solubilities depend on various factors such as the concentration of the reactants, pH, temperature, and other environmental conditions.
