25. Explain the following terms with one example each.
(a) Corrosion
(b) Rancidity
Answers
Explanation:
Corrosion is a natural process that converts a refined metal into a more chemically stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.
Example :- Rusting of iron and steel is perhaps the most common example of metallic corrosion
Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour.
Example :-when a chips pack is exposed to atmospheric air which results in a change in taste and odor.
Answer:
Corrosion is usually defined as the degradation of metals due to an electrochemical process. The formation of rust on iro, tarnish on silver, and the blue green patina that develops on copper are all examples of corrosion.
Rancidity in a condition in which the substance with oil and fat gets oxidized when they are exposed to air. An example of rancidity is when a chips packs is exposed to atmospheric air which results in a change in taste and odor
