How corrosion works
Web12 de fev. de 2024 · Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases. WebCorrosion occurs when atoms of the entire metallic surface become oxidized as a reaction to their environment. Hence, metals that are easily oxidized tend to corrode …
