Question

Which of the following products are obtained when Na2Co3 is added to a solution of copper sulphate?​

Answer 1

2CuSO4 + 2Na2CO3 + H2O → Cu2(OH)2CO3 + 2Na2SO4 + CO2

Copper sulphate react with sodium carbonate and water to produce copper hydroxocarbonate, sodium sulfate and carbon dioxide.

Answer 2

Answer:

Copper sulpate is a blue solid (it exists as the pentahydrate) and readily dissolves in water to make a blue solution containing Cu2+ ions and SO4^2- ions. Sodium carbonate is a white solid and dissolves in water to make Na+ ions and CO3^2- ions.

When combined, these two solutions will react to form an insoluble compound:

2CuSO4(aq) + 2Na2CO3(aq) + H2O(l) → Cu2CO3(OH)2(s) + CO2(g) + 2Na2SO4(aq)
