Question

how is the air dissolved in water different from ordinary air

Answer 1

The ordinary air consists of Nitrogen (78%), Oxygen (21%) , carbon dioxide (0.01%) and other various gases.
Some of the gases like oxygen,nitrogen and carbon dioxide dissolve in water.
Solubility of air in water or any other medium largely depends upon temperature..
For example,in water, Oxygen dissolves the least that is it is about 10mg/L
Nitrogen dissolves about 20mg/L..

We can say that air dissolves just about 30mg/L in water... Just compare it with concentration of ordinary air...


We arrive at an conclusion that solubility of gases largely depends upon the temperature

Answer 2

Explanation:

Since oxygen is more soluble in water compared to nitrogen, composition of the air dissolved in water different from ordinary air.
