    Superprofwhat Colour Change Would You Observe During This Reaction?What Is The Reaction Between Copper Carbonate And Sulphuric

    mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt. copper ( the salt formed depends on the acid used, in this case it is sulfuric acid which will form sulfates. the metal carbonate used is copper carbonate and so the copper carbonate reacts with sulphuric acid (reactants) giving rise to copper sulfate (cuso4) (residue, powder), carbon dioxide (co2)(gas) and water (h2o)( the reaction between copper carbonate and sulphuric acid will be a neutralization reaction. copper carbonate will acts as a base, however, sulphuric acid is ,does copper react with dilute sulfuric acid? why?,sulphuric acid to liberate sulphur dioxide gas as per the equation — hope it why is an excess of copper oxide added to acid when it's used to make salt?
