Explain the formation of rust. Give the chemical equation also
Answers
Answer:
Formation of Rust :
Rusting is an oxidation reaction.
The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.
Iron and steel rust when they come into contact with water and oxygen –
both are needed for rusting to occur.
The chemical formula for rust is : Fe2O3
Commonly known as ferric oxide or iron oxide.
The final product in a series of chemical reactions is simplified below as-
The rusting of iron formula is simply
4Fe + 3O2 + 6H2O → 4Fe(OH)3.
The rusting process requires both the elements of oxygen and water.
Answer:
You must have seen that if you leave an Iron object such as a trowels an Iron lock out in the rain, a reddish brown layer is deposited on its surface after a few days.This layer is called rust and this process is called rusting.This layer of rust falls off gradually, exposing fresh metal to further rusting. With the passage of time , an Iron object becomes weak.
☆Iron reacts with atmospheric Oxygen in the presence of moisture to form a substance called Iron oxide, which we call as rust
Iron+oxygen+water-------->Iron oxide.
Fe+O2+H2O------>Fe2O3.xH2O.
