Question

Argon is the major constituent of inert gases present in air:
(A) true
(B) false

Answer 1

Hint: To solve this question we will consider the chemical properties of argon and its abundance in nature. Also, about the economic factor of argon if it is economically reliable to use it as an inert gas.

Complete Solution :
- So, we have been provided with a statement which is that argon is the major constituent of inert gases present in air,
We need to tell whether the statement is true or not.
So, for that:
- Firstly, we know that argon is a noble gas which is colourless, odorless and tasteless. It is non-toxic but still it is 38 percent denser than air so it is considered as a dangerous gas for closed areas.
- Argon is the only noble gas present in the air because it is obtained from the air as a byproduct when oxygen and nitrogen are produced.
- Whenever an inert atmosphere is needed, argon is used, The most common gases used as inert gases in the atmosphere are purified argon and nitrogen gases, this is because of their high abundance and low cost.
- Argon is the most used noble gas. And as it is unreactive so it would prevent chemical reaction of the hot metal being welded. And this is the reason that chief ores of argon are used in metallurgy. As it can easily provide us with an inert atmosphere. So, that’s why argon is the major constituent of inert gases present in air. So, from this we can conclude that the statement given to us is true.

Note: Inhalation of argon gas in excessive amounts can lead to dizziness, nausea, vomiting, loss of consciousness and even death.
