Which of the following gases can be used for storage of fresh sample of an oil for a long time?
(a) Carbon dioxide or oxygen
(b) Nitrogen or oxygen
(c) Carbon dioxide or helium
(d) Helium or nitrogen
Answers (1)
Ans. (d)
Helium can be used as it is an inert gas. Nitrogen is less reactive and it is cheaper than Helium.
Hence Helium, just as nitrogen, can be used for storage of a fresh sample of an oil for quite a while on the grounds that they avoid the oil from rancidity.
The contact of air and oil is forestalled by utilizing nitrogen or helium as covering gas.
