Does oxygen differ in different types of water source?

Question

water sources: lakes, tap water, rain water, ocean, pond, etc.

does it differ in oxygen levels?

Answer 1

Yes - different water sources will naturally have different amounts of dissolved oxygen. The oxygen itself isn't any different but the amount of it in the water is.

Water with more solute (like the salt in ocean water or the minerals in tap water, or the bits of dissolved detritus in lakes or ponds) will have a lower concentration of dissolved oxygen. However, there are also other factors, including temperature, local atmospheric pressure, and pH of the water, among others, that affect the oxygen content.

Answer 2

I'm not entirely sure what you're trying to ask, but I'll take a swing:

The oxygen in all water molecules is plain old oxygen. There are different isotopes of oxygen (oxygen atoms that weigh more or less than the most common kind), but they occur at the same rate in tap water as they do in the ocean.

Water is water is water. Oxygen is oxygen is oxygen.

Answer 3

The only difference would be in isotopic composition, and as far as I know, O-16 is the only stable oxygen. The waters differ because of other factors, particularly chemicals dissolved in the water, including oxygen itself.

Answer 4

all water is H2O. different sources may have other molecules mixed in with them such as rain water may have air pollutants in it, ocean has salt and so on but the water itself still contains the same amount of oxygen.

Answer 5

no water is H2O if it is a different scouce of water like salt water you just add salt if you added an atom to oxygen it wouldnt be water anymore like H2O2 it would become hydrogen peroxide
