hereogeneous mixtures
Because air is made up of a bunch of different other gases: Hydrogen, Oxygen, Nitrogen, etc. But is done so in a way, that you cannot see all the different parts. Therefore, air is not an element, nor a compound, nor a heterogenous mixture (since you can visibly see all the parts of air), but rather a solution.
air is mixed with other substances
A compound differs from a mixture in that a compound always has a
Salt water is classified as a mixture due to the variability of its contents.
Any solution that has a pH below 7 is classified as acidic.
No. Oil and water would form a heterogeneous mixture. A solution is a homogeneous mixture.
The water solution having [OH-] = 3.2 X 10-5 has a pOH of 4.495, that is, a pH of 9.505. So, it is a basic solution.
This is a homogeneous solution.
alkaline solution
A solution classified as: Uniform mixture .
No a solution
CO2(aq) because a solution means the substance is dissolved in water.

why is air considered a solution
It is a solution.
No, it is a solute.
Small particle that is a building block of matter
Simple: a true solution of a salt in water or another solvent.
