All other trademarks and copyrights are the property of their respective owners. Reaction of metals with water Some metals also react with water, but like their reaction with oxygen, they react in different ways. This does not protect the iron surface to further reaction since it flakes off, exposing more iron metal to oxidation. Copper metal reacts with hot concentrated sulfuric acid solution to form aqueous copper (II) sulfate, sulfur dioxide gas and water. If it is bonded to atoms with much lower electronegativity, then it is usually considered reduced. If an atom is bonded to strongly electronegative atoms, then in most cases it is considered oxidized. For example, the oxygen atom in water behaves like it has a 2- charge while the hydrogen atoms behave like they have 1+ charges. Reaction of copper with acids.
