FACTS ABOUT CORROSION
cool cool
100
This substance contributes to corrosion in addition to oxygen.
What is Water?
100
This is a method of corrosion prevention in which forces the iron to become the cathode by supplying the iron with electrons.
What is Cathodic Prevention?
100
These two categories are methods used for preventing or minimizing the corrosion of iron.
What is Protective coatings and the method of cathodic prevention?
100
This substance is red-brown in colour.
What is Rust?

(two correct answers)

Zambies and carbonara

300
The corrosion of this metal is not a major problem compared to the corrosion of Iron.
What is Aluminum?
300
This system is routinely protected by a coating supplemented with cathodic protection.
What is a pipeline?
300
This metal is used to protect the iron when it is galvanized.
What is Zinc?
300
Little to no corrosion occurs if iron is kept in this type of environment.

What is Fe(s) -> Fe2+(aq) + 2e-
400
This is an electric current forced to flow toward an iron object by an external potential difference.
What is an Impressed Current?
400
This physical protection method provides a protective layer and preferential corrosion of zinc.

What is Fe2O3 x xH2O(s)?
500
This metal is more easily oxidized than iron and connected to the iron object to be protected.
What is a Sacrificial Anode?
500
These two metals are used as metallic coatings.
What is tin and zinc.
500
This electrochemical process involves a reaction of metal and its environment, returning to metal to its ore-like state.
What is Corrosion?
