Why does water rust?

Answer 1

Iron corrodes to form an iron oxide. This oxide is commonly called rust. The reaction involves a transfer of electrons from iron to oxygen. Water is commonly slightly acidic due to the carbon dioxide in the atmosphere. The acid brings hydrogen ions in contact with the iron which allows the formation of an iron hydroxide intermediary compound which hastens the formation of iron oxide, rust. Ships at the bottom of the ocean rust more slowly as there is less oxygen and the water is less acidic. The only way to prevent rust forming is to prevent oxygen coming in contact with the iron through the application of paint, oil, plastic or another metal.

Answer 2

You must add salt in water because water molecules are closely bonded then salt helps in breaking water molecules and after adding salt water is able to penetrate inside the metal then the metal rust.

Answer 3

Water itself does not rust. Rusting is a process that occurs when iron is exposed to oxygen and moisture, creating iron oxide, commonly known as rust. When water comes into contact with iron or steel, it can facilitate the rusting process by acting as an electrolyte, allowing the flow of electrons between the metal and oxygen in the air, leading to the formation of rust.

Answer 4

Water helps metal rust because Kouta is a mad dog and Beamer goes offa bruva

Answer 5

When the water makes the metal rust the oxidation will go on top of the metal and rust.

Answer 6

Water does not rust the ferrous metal it comes into contact rusts
