what is corrosion? explain its advantages and disadvantages,....
Answers
Answer:
Corrosion is the irreversible damage or destruction of living tissue or material due to a chemical or electrochemical reaction.
advantages:-Protection : Surface corrosion forms an oxide layer which further protects the inner metal form corrosion.
Corrosion prevents corrosion : Some metals like zinc are used as sacrificial anodes to prevent corrosion to other metal.
Galvanic corrosion : The principle on which primary batteries work. In which one metal corrodes preferentially to another when both metals are in electrical contact, in the presence of an electrolyte.
disadvantages:-Lose of metal from the surface.
Change in the physical appearance of a metal object.
Change in chemical properties of metal.
Lose of the efficiency of metallic machines.
A decrease in the life span of metallic objects.HOPE IT HELPS

ADVANTAGES OF COROSION:-
There are some advantahes of corrosion Surface corrosion forms an oxide layer. It acts as a barrier for air and moisture and thereby preventing the inner metal fromcorrosion. Some metals like zinc act as saccificial anodes to prevent corrosion to other metals.
