Is air a pure mixture?

Air is a mixture of many elements in just the proper proportions to sustain human existence on Earth. Hence it is not a pure material. A pure material has the same chemical makeup throughout its entire life cycle. Ir is a combination of nitrogen and oxygen, accounting for 78% of the total (20 percent ). However, because air contains various gases in varying proportions, we refer to it as a mixture rather than a pure entity.

How does the composition of the air change as you rise?

The composition of the air also changes as one rises in altitude. Over 90 kilometers above the Earth’s surface, oxygen molecules disintegrate , leaving only oxygen atoms. Nitrogen molecules decay over a hundred kilometers above the Earth’s surface. At this altitude, the air does not have the same composition as it does at ground level. There is a very distinct difference in the atmosphere.

Is air a heterogeneous mixture?

In detail it's a heteregenous mixture. A heterogeneous mixture is simply any mixture that is not uniform in composition. One might think there is 78% nitrogen, 21% oxygen etc so why say that it has a non uniform composition ???? The answer is quite simple. We take estimated values of the constituents of air. They are actually never present in those ratios at all

Is air a compound or mixture?

So is the case with air. While N 2, O 2, C O 2 are pure compounds, air consists of these compounds in varying ratio. Hence, air in not a compound, but is a mixture.
