$\implies$

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.

$\implies$There are several cost effective ways to prevent corrosion including:

• Use non-corrosive metals, such as stainless steel or aluminium

• Make sure the metal surface stays clean and dry

• Use drying agents

• Use a coating or barrier product such as grease, oil, paint or carbon fibre coating

• Lay a layer of backfill, for example limestone, with underground piping

• Use a sacrificial anode to provide a cathodic protection system

$\implies$Rancidification is the process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor.

$\implies$Rancidity can be prevented using the following methods:

• Adding antioxidants (substances which prevent oxidation) to food.

• Storing food in airtight containers to slow the process of rancidification.

• Refrigerating food also helps to slow down rancidification.

• Replacing oxygen in the containers with another gas.
