Reactions with metal oxides
Reactions with metal oxidesA salt and water are produced when acids react with metal oxides . Metal oxides are bases , because they neutralise acids.
Those transition metal oxides with oxidation numbers +4, +5, +6, and +7 behave as covalent compounds containing covalent metal-oxygen bonds. ... The oxides with oxidation numbers of +5, +6, and +7 are acidic and react with solutions of hydroxide to form salts and water; for example, CrO3 + 2OH- → CrO42− + H2O.

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.
