Question

we dissolve oxygen into water​

Answer 1

Answer:

Dissolved oxygen (DO) is oxygen gas (O2) that is dissolved in water. Gases in the atmosphere, such as oxygen, nitrogen and carbon dioxide, naturally dissolve in water to some degree. Like salt or sugar, these gases are invisible in water once they become dissolved. The element oxygen exists in many forms in nature

Answer:

Dissolved oxygen (DO) is oxygen gas (O2) that is dissolved in water. Gases in the atmosphere, such as oxygen, nitrogen and carbon dioxide, naturally dissolve in water to some degree. Like salt or sugar, these gases are invisible in water once they become dissolved.

The element oxygen exists in many forms in nature. Although most people know that oxygen is part of the water molecule, most would be surprised to hear that oxygen is also the most abundant element in rocks. In these forms, oxygen is bound to other elements such as hydrogen, silicon or carbon. Molecular oxygen (O2), which is in air, is different than other forms because it is not bound to other elements. In nature, the O2 that we breathe is chemically much more reactive than the more abundant forms of oxygen that we come in contact with. This is what allows plants, animals and other organisms to use O2 to metabolize their food through the process of respiration.
