I’ve never really understood how that works. Chemistry wasn’t my best subject in high school, and it’s been over a decade since then for me.
Dissolved oxygen is not the same as the oxygen in water molecule. Think of the fizz in soda. That comes from the dissolved carbon dioxide. You can have soda that is flat and that is very sharp. The same way you can have water with less dissolved oxygen or more.
In more technical terms, think of dissolved oxygen/carbon dioxide as gas molecules held in cage of water molecules. The more cages you make, the more you can dissolve these gases until you reach the maximum amount possible at a given temperature/pressure.
Good explanation!
Happy to help :) Thank you.
Funny thing is, it’s the more technical explanation you gave that helped me understand it better. Like, it clicked with me when I visualized molecular cages wrapping around other molecules. :D
I am happy that my undergrad degree in chemistry is helpful somehow :) I have found that often stem people underestimate how much others can understand.
Water molecules are H2O, but any body water is more than just water.
It works the same as salt etc being in the waterbody
