What can be said about the solubility of oxygen in water?

Oxygen has relatively low solubility in water compared to many other gases. While it can dissolve in water, the amount that can dissolve is limited, which means that it doesn't readily mix or form a solution in significant quantities. This property is important for aquatic life because organisms such as fish rely on dissolved oxygen for respiration.

In general, gases like carbon dioxide and ammonia are more soluble than oxygen, which contributes to organisms' dependency on water bodies to provide sufficient dissolved oxygen levels. This low solubility of oxygen in water highlights the need for oxygen-producing processes, such as photosynthesis in plants, to maintain adequate levels for aquatic ecosystems.
