Question

In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of:

• A. $C{l}_2$
• B. $H_2$
• C. $N_2$
• D. $O_2$

Answer 1

Answer: (C)

$N_2$

In order to prevent the spoilage of potato chips, they are packed in plastic bags in an atmosphere of $N_2$ to prevent from being rancid or oxidised.
Nitrogen is added to the potato chip packet to add strength to the packaging. Normally aluminium cans are used for packaging beverages, these beverages are carbonated drinks and the carbon dioxide present in them provides the internal pressure in the can and thus gives internal strength to the aluminium can. But in non-carbonated drinks, there is no carbon dioxide present and so Nitrogen is added to it to give the required strength to the packing.
