Metal oxide reacts with acids to give salt and water . Let us consider the rxn of copper oxide with dilute HCL
CuO + 2 HCL --- CuCl2 + H2O
After the rxn takes place the colour of solutions becomes blue -green due to the formation of copper
(ll) Chloride and the copper oxide dissolve. this prove that mettalic oxide are basic oxides .

Reaction of metallic oxides with acids
Metallic oxides react with acids to give salts and water. Let us consider the reaction of copper oxide with dilute hydrochloric acid.
After the reaction takes place the colour of the solution becomes blue-green due to the formation of copper (II) chloride and the copper oxide dissolves. This proves that metallic oxides are basic oxides.
