Question

Why does Iron rust ? how can it be prevented ? describe two methods to prevent rusting .​

Answer 1

Answer:

Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion)

Explanation:

(a) The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface.

(b) Galvanisation is another method of protecting iron from rusting by coating it with a thin layer of zinc.

hope it's helpful

Answer 2

If left unused or stationary, several metallic materials suffer chemical changes on their surface over time. Corrosion is the term for these changes.

Explanation:

The following are the methods for preventing iron from rusting:

• Oiling, painting, or greasing: When we apply oil, grease, or paint to a surface, it becomes waterproof, preventing moisture and oxygen from coming into direct contact with the iron. As a result, corrosion can be avoided.

• Galvanization: When a layer of zinc metal is applied to an iron product, it prevents the iron from coming into contact with oxygen and moisture.

Rusting can be avoided in this manner.

• By alloying, which is the process of combining iron with another metal or non-metal to prevent rusting.
