What is corrosion? Do gold ornaments corrode? Justify
Answers
Answer:
Corrosion is a natural process that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulphide.
Gold is one of the least reactive metals. It is unaffected by air, moisture, sweat, or common contaminants found in the air or water. As a result, it does not corrode.
Explanation:
Electrochemical processes cause the most frequent types of corrosion. When the majority of all of the atoms on the same metal surface is oxidized, the entire surface is harmed. The majority of metals are easily oxidized, meaning they lose electrons to oxygen (and other chemicals) in the air or water. When oxygen is reduced (gains electrons), it reacts with the metal to form an oxide.
Gold jewellery does not corrode. Because gold is a weaker reducing agent, it is difficult to oxidize.
