Difference between corrosion and rusting ?

Question

Answer

Answer

Corrosion:- जब कोई metal oxidize हो जाता है और अपने properties को loose कर देता है तो उसे corrosion कहते है।

Rusting:- जब iron में corrosion होता है तो उसे rusting कहते हैं।

Answer

Corrosion and rusting are two different terms expressing the same idea. Corrosion is a type of oxidation. Rusting is a type of corrosion. Corrosion can occur on metal surfaces as well as on nonmetal surfaces. Corrosion can be caused by either the exposure to air and moisture or the spread of chemicals on the surface. Rusting is the chemical process of forming a red-orange coating on the surface of iron or steel. It is an oxidation. The main difference between corrosion and rusting is that corrosion can happen due to chemicals whereas rusting does not happen due to chemicals although it can be accelerated by some chemicals.

Answer

CORROSION:---
corrosion is the process in which metal are eaten of grandly by the action of air moisture or a chemical on their surface

RUSTING :---
when an iron object is left in damp air fof a considerable time it get covered with a Red Brown flaky substance called rust this is called rusting of iron

Answer

When metals are eaten up by outside forces such as moisture or acid they are said to corrode and the process is called corrison.
rusting is particular name given to corrison of iron. it is known as hydrated iron oxide with a formula of:
Fe(2)O(3).xh(2)O
here x is the number of water of crystallisation. which is not defined.

Answer

What is Corrosion?

Corrosion is a natural process that occurs when metals are exposed to environmental factors such as moisture, air, and chemicals. It is a gradual degradation of metals due to chemical reactions with their surroundings. Corrosion can affect various metals and alloys, including iron, steel, aluminum, and copper.

What is Rusting?

Rusting is a specific form of corrosion that occurs when iron or its alloys, such as steel, undergo corrosion. It is a visible form of oxidation where iron reacts with oxygen and water to form hydrated iron(III) oxide, commonly known as rust. Rusting is a common phenomenon that affects iron and steel objects exposed to moisture and air.

Key Differences between Corrosion and Rusting:

1. Definition:
- Corrosion: Corrosion refers to the degradation of metals due to chemical reactions with the environment.
- Rusting: Rusting is a specific type of corrosion that occurs when iron or its alloys react with oxygen and water.

2. Metals Affected:
- Corrosion: Corrosion can affect various metals and alloys, including iron, steel, aluminum, copper, and more.
- Rusting: Rusting specifically affects iron and iron-based alloys like steel.

3. Chemical Reactions:
- Corrosion: Corrosion involves various chemical reactions that depend on the metal and environmental factors present.
- Rusting: Rusting is a specific chemical reaction where iron reacts with oxygen in the presence of water, forming hydrated iron(III) oxide or rust (Fe2O3·nH2O).

4. Appearance:
- Corrosion: Corrosion can manifest in different forms depending on the metal and environmental conditions. It can include tarnishing, pitting, cracking, or general surface degradation.
- Rusting: Rusting specifically refers to the formation of a reddish-brown flaky layer on the surface of iron or steel objects.

5. Impact:
- Corrosion: Corrosion can affect the structural integrity, functionality, and aesthetics of metals, leading to potential damage and reduced lifespan.
- Rusting: Rusting weakens iron and steel objects, making them brittle and prone to structural failures. It also causes discoloration and degradation of the affected surfaces.

Conclusion:
Corrosion is a broader term that encompasses the degradation of various metals, while rusting specifically refers to the corrosion of iron and iron-based alloys. Rusting occurs when iron reacts with oxygen and water, forming rust. Corrosion, including rusting, can have detrimental effects on the appearance, strength, and durability of metals, making preventive measures essential to mitigate its impact.
