Answer:
(a) 2H₂SO₄ + Cu → CuSO₄ + 2H₂O + SO₂
Explanation:
, if you react copper(I) oxide with hot dilute sulphuric acid, you might expect to get a solution of copper(I) sulphate and water produced. In fact you get a brown precipitate of copper and a blue solution of copper(II) sulphate because of the disproportionation reaction.
Hope this will help you.
