I Rusting of iron can be prevented by galvanization.
State two ways to prevent the rusting of iron. Fe 2 O 3 reacts with water and forms Fe 2 O 3. In this process iron articles are coated with a thin layer of zinc metal which prevent the iron to come in contact with air and moisture. Rust is developed from two different iron oxides that are different due to their oxidation state in the iron atom.
Hence oxygen is responsible for oxidation of iron and therefore forms rust. This film protects the article from rusting. Providing the metals with an electric charge can help inhibit the electrochemical reactions that lead to rusting.
This is why if you live near a beach the metals seem to rust faster. I Painting or Oiling. Rusting of iron reaction.
Rusting requires moisture and oxygen. By applying oil grease or paint the surface becomes water proof and the moisture and oxygen present in the air cannot come into direct contact with iron. When iron articles are dipped into a boiling and strongly alkaline solution of sodium phosphate a protective insoluble film of iron phosphate is formed on them.
Basically oil or grease form a protective layer over iron just. Iron II oxide or ferrous oxide - The oxidation state of iron in this compound is 2 and its chemical. Oiling greasing or painting.
3 Install a dehumidifier in humid rooms where metal items are. Coat it with Oil - Use of oil or grease significantly reduces the chances of developing rust in iron. List in tabular form any three chemical on the basis of which metals and non-metals are differentiated.
