Answer :

Corrosion is defined as a process where materials, usually metals, deteriorate as a result of a chemical reaction with air, moisture, chemicals, etc.

For example, iron, in the presence of moisture, reacts with oxygen to form hydrated iron oxide.

4Fe + 3O2 + nH2O → 2Fe2O3.nH2O

Rancidity is the process of oxidation of fats and oils that can be easily noticed by the change in taste and smell is known as rancidity.

For example, the taste and smell of butter changes when kept for long.

Hope it's helpful to you!!!!!

hi dear....

CORROSION is the process in which metals are slowly eaten up by the action of chemicals or air moisture

e.g :- rusting.

RANCIDITY is the process that, when the substance containing oils and fats are exposed to air, they get oxidised and become rancid due to which their smell, taste and colour change.

e.g:- when a butter is kept open for a long time then its smell and taste gets changed.

hope it helps....
