Question

c) State how can you convert cupric oxide to copper sulphate. Explain with equation and name the process.​

Answer 1

Chemical Equation

CuO(s) + H2SO4 (aq) → CuSO4 (aq) + H2O(l)

The sulfuric acid reacts directly with the copper oxide. In many cases, copper needs to be oxidised to react with an acid, but in this case the copper is already oxidised. Because sulfuric acid itself is an oxidiser, copper sulfate also would have been formed if copper metal was used. In the reaction, copper sulfate and water are produced. The copper sulfate will be in solution because of its high solubility.
