Questions
Define corrosion.
Define the following term:
Corrosion
Advertisements
Solution 1
When a metal is attacked by substances around it, such as moisture, acids, etc., it is said to corrode, and this process is called corrosion.
Solution 2
Corrosion is an electrochemical process in which a metal is oxidised to a metal oxide or another salt of the metal by losing electrons to oxygen or another electronegative element, forming a coating on the metal surface.
RELATED QUESTIONS
