what is corrison explain it
Answers
Answer:
Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. ... In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen or sulfates.
Answer:
• Corrosion is defined as the process in which the surface of the metals are oxidized in the presence of oxygen and the surface of such metals are destroyed in the process.
Explanation:
• Corrosion can happen in any metal surfaces but most commonly seen in iron, zinc surfaces.
• Although the process of corrosion in case of iron is known as Rusting.
• Corrosion first effects the surface of the metals and the shine and lustre of the metal is destroyed, instead a layer is formed over the corroded surface.
• If this corrosion is not stopped at the beginning then the whole of the metal surfaces gets destructed by it.
• It is an irreversible process, therefore the only way to prevent it from happening and destroying metals is to avoid keeping the metal in conditions which promotes corrosion.
• These conditions are presence of moisture, that is water ( especially salt water), presence of gases like carbon dioxide, sulphur dioxide, etc.
• And prevention of corrosion includes electroplating in which a layer of less reactive metal is plated around the metal like iron, zinc etc to lower it's reactivity.
