- When a metal is attacked by substances around it such as moisture, acids, etc., it is said to be corroded and this process is called corrosion. The black coating on silver and the green coating on copper are examples of corrosion.
- Corrosion causes damage to car bodies, bridges, iron railings, ships and to all objects made up of metals, especially those of iron. When fats and oils are oxidised, they become rancid and their smell and taste change.
- Usually substances which prevent oxidation (antioxidants) are added to foods containing fats and oil. Keeping food in air tight containers helps to slow down oxidation. Due to this reason, bags of chips are flushed with gas such as nitrogen to prevent the chips from getting oxidised.

Regarding the oxidation, consider the following statements: 1. The Bl...
Explanation:
1. Corrosion:
- The black coating on silver and the green coating on copper are examples of corrosion.
- Corrosion is the process of deterioration of a metal due to chemical reactions between the metal and its environment.
- The black coating on silver is known as tarnish, which is a form of corrosion caused by the reaction of silver with sulfur compounds in the air.
- The green coating on copper is known as patina, which is a form of corrosion caused by the reaction of copper with oxygen and other chemicals in the environment.
2. Preventing Oxidation:
- Bags of chips are flushed with gas such as nitrogen to prevent the chips from getting oxidized.
- Oxygen is a common oxidizing agent that can cause food products like chips to become rancid or stale.
- By flushing the bags with nitrogen, the oxygen content inside the bag is reduced, thus slowing down the oxidation process and keeping the chips fresh for a longer period.
Therefore, both statements are correct as they relate to different aspects of oxidation and corrosion. The black coating on silver and the green coating on copper are examples of corrosion, while flushing bags of chips with gas such as nitrogen helps prevent oxidation.
