Type your answer here... most of the metals naturally exist in combined formed during Metallurgy the metals are extracted from their ores by reduction process in pure metallic state, metals are unstable and considered to be in the excited state.therefore,the extracted metals have a tendency to go to thermodynamically stable state , which is otherwise known as corrosion.

What is metal corrosion?
Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.
What type of reaction is occurring when a metal undergoes corrosion?
Oxidation reduction
What is liberation in mineral extraction?
liberation itself refers to liberate , the process of separation of the metal and impurity from the compound of mineral is called liberation in mineral extraction
The reaction of a metal with oxygen to form rust is called?
Metal Oxide is the general term for reaction with oxygen. Rust is usually a specific referral to Iron Oxide Fe2O3. This process is called oxidation.
What are examples of amphoteric oxides?
From the USDOT Pipeline and Hazardous Materials Safety Administration Glossary: A metal that is susceptible to corrosion in both acid and alkaline environments. Aluminum is an example of an amphoteric metal.
What is immersed corrosion?
Immersed Corrosion refers to a type of metal corrosion when the metal is immersed in a liquid.
Why corrosion is reverse of extractive metallurgy?
process of corrosion nd formation of oxide film is just reverse as in extractive metallurgy of metals.
What type of change is rust formed into iron after exposure to air?
Corrosion is the reverse of the change of state in your question. Rust is corroded metal [ iron, steel ].
What is metal corrosion?
Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.
Is corrosion of aluminum metal a chemical?
Corrosion is a chemical process.
What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
Is rust a form of corrosion?
Yes. Rust is oxidation of the metal, a form of corrosion (chemical destruction) that weakens metal.
Which metal could be used to coat another metal to protect it from corrosion?
Tin could be used to coat another metal. It is done to prevent corrosion.
Is Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
What is corrosive?
Corrosion is a chemical reaction in which molecules break down due to a chemical reaction with its surroundings. Most often, corrosion is the electro-chemical oxidation of a metal (such as iron "corroding" to form iron oxide, a.k.a. rust). Corrosion is deterioration of a substance, usually metal. Corrosion is slow and continuous eating away of metal by the surrounding.
How does paint work to stop corrosion of metal?
The paint prevents the metal from coming in direct contact with air and moisture, which are what cause corrosion.
Is corrosion of iron useful?
Corrosion is not useful for any metal; an exception is electrocorrosion processing.
