Question

Is air a mixture or a compound? Give three reasons for your answer.

Answer 1

Air is a mixture and not a compound because of the following reasons:

• Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air.
• Air shows the properties of all the gases present in it. For Example: Air supports combustion because of oxygen present in the air.
• Air has a variable composition because at different places the different amount of gases are present in the air.
