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

Hi Friend...


We know ordinary air is mainly composed of three gases such as nitrogen(78%),oxygen(21%) and carbondioxide (0.03%).
Water can dissolve gases like oxygen and nitrogen to a small extent due to which amount of these gases dissolved in water will be little as compared to present in ordinary air.
Water can dissolve CO2 to greater extent due to the formation of carbonic acid (H2CO3).
So,water contains CO2 gas more than nitrogen and oxygen gases.
