What is corrosion ??
Answers
Answer:
Corrosion is the process of rusting of iron in the presence of water and air.
Explanation:
Corrosion is a natural process in which a refined metal is converted to a more chemically stable form, such as oxide, hydroxide, or sulphide. It is the gradual decomposition of materials (usually metals) as a result of chemical and/or electrochemical reactions with their surroundings.
Corrosion is the gradual deterioration of metals caused by the action of air, moisture, or a chemical reaction (such as an acid) on their surface. Rusting of iron, or the forming of a brown flaky material on iron objects when exposed to moist air, is the most common example of metal corrosion.
As metals are exposed to the elements, they react with the air or water in the atmosphere to produce unwanted compounds. Corrosion is the term for this operation. The atmosphere attacks the least active metals, such as gold, platinum, and palladium.
Corrosion Explanation
Corrosion occurs when a refined metal is naturally converted to a more solid form, such as oxide, hydroxide, or sulphide , causing the substance to deteriorate. Corrosion can cause natural and historic monuments to deteriorate significantly, as well as increase the likelihood of catastrophic equipment failures. Corrosion is caused by air pollution, which is getting worse around the world.
Alkali metals, such as sodium, must be contained in oil because they corrode rapidly. Roofs are made of less reactive metals like lead and copper. Lead corrodes to form a white lead oxide or carbonate, while copper (Cu) corrodes to form a simple green carbonate. When metal reacts with another element, such as oxygen, hydrogen, electricity, or even dirt and bacteria, it corrodes. Corrosion may also occur when metals, such as steel, are subjected to excessive stress, which causes the material to crack.
