Question

What is called rusting.?

Answer 1

Answer:

Rust is another name for iron oxide, which occurs when iron or an alloy that contains iron, like steel, is exposed to oxygen and moisture for a long period of time. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the bonds of the metal itself.

Answer 2

Explanation:

• Rusting :-> The dgredation of metal due to presence of moisture or many different reacting gases results the formation of oxide and hydroxide .
• Rusting decrease the strength of metal .
• To metal from rusting gelvenigetion , electroplating , painting etc done on metal surface .
• How rusting occur ?

• Due to formation anode(presence of oxygen more) and cathode(presence of oxygen is less ) region in metal surface the rusting takes place .The following characteristics of rustingn are
• The electron transfer from anode to cathode.
• The oxidation occur at anode .
• The reduction occur at cathode
• the oxidation occured due to exchange of electron between two region of metal surface .
