Question

short notes on corrosion and rancidity​

Answer 1

Answer:

Corrosion is the process in which any metal gets corroded due to presence of oxygen, moisture, etc.

Rancidity is the process in which any metal gets  rancid due to presence of oxygen, moisture, etc.

Answer 2

Corrosion:

• Corrosion is a chemical reaction which involves the surface of a metal changing from an element to a compound.
• Corrosion progressively weakens a metal and eventually destroys it.
• Most metals corrode but different metals corrode at different rate.

Rancidity:

• It is the natural process of decomposition of fats or oils by either hydrolysis or oxidation, or both.
• The process of degradation converts fatty acid esters of oil into free fatty acids.
• This gives rise to an unpleasant odour and taste in food.
