Given substances: gold, zinc oxide, iron, copper (II) oxide. With which of them will the sulfuric acid solution react? Write the reaction equation and indicate the name of the salts formed.
ZnO + H2SO4 == ZnSO4 + H2O (zinc sulfate)
Fe + H2SO4 == FeSO4 + H2 (iron II sulfate)
CuO + H2SO4 == CuSO4 + H2O (copper sulfate)
There will be no reaction with gold due to its inertness to the action of sulfuric acid and any other simple inorganic acid.
