Define rusting of iron and its mechanism

 Rusting of Iron:

Definition: 

• The process of corrosion that occurs when iron reacts with water and air to form iron oxide, also known as rust.

 Mechanism of rusting: 

• Rusting is a natural process that happens when iron or steel is exposed to air and water.
• The process of rusting is also known as corrosion.
• Rust is formed when iron reacts with oxygen in the air, which forms iron oxide or rust.
• The presence of water is essential for rusting to occur, as it helps to speed up the reaction between iron and oxygen.
• Rusting can happen faster in areas with high humidity, salty water, or acidic conditions.
• Rusting weakens the metal by causing it to flake and peel away, which can lead to structural damage.
• Rust can also discolor surfaces, making them look unsightly.
• Rust can be prevented by using rust-resistant coatings or by keeping the metal dry.
• Regular cleaning and maintenance can also help prevent rust from forming.
• Rust removal can be done by using a wire brush or sandpaper to scrub away the rust, or by using rust removers that contain chemicals to dissolve the rust.
