The reaction between copper sulfate CuSO and sodium carbonate NaCO is a double displacement reaction, where the cations and anions of the two reactants switch places to form new products. The products formed are copper carbonate CuCO and sodium sulfate NaSO .The balanced chemical equation for the reaction is:CuSO aq + NaCO aq CuCO s + NaSO aq In this reaction, copper sulfate and sodium carbonate are both in aqueous form, meaning they are dissolved in water. Copper carbonate is a solid product that precipitates out of the solution, while sodium sulfate remains dissolved in water as an aqueous product.
