It is disolved air because it is contained in the water, and is not free air in the atmosphere.
Most bubbles in water are carbon dioxide. In a carbonated drink, this carbon dioxide gas that is put in the water (or Coke) under pressure, when the pressure is released the bubbles form. Even in pond water, the bubbles are likely caused by some small animal.
Not at all. The reason is because oxygen is fairly soluble in water but very soluble in alkaline pyrogalol.
Atmospheric air. Air bubbles are simply dissolved air coming out of solution.
No, not specifically, intentionally or naturally.
what temperature is ocean water likely to contain more dissolved salts 30 degrees or 15 degrees
Tears may contain loose cells (which contain DNA), but it is mostly just water and dissolved salts.

An aqeous solution contain a solute dissolved in water.
Seltzer water contain carbon dioxide; bubble water may contain and another gases, including air.
carbon dioxide
Dissolved in water, e/g/ atmospheric CO2 into rain-water.
Salt water contain dissolved sodium chloride.
In caves formed in limestone - as are most of the world's caves although not all such caves contain stalagmites and stalactites. They are precipitations of calcite dissolved from the host limestone by carbonic acid - rain water acidified by atmospheric carbon dioxide dissolved in it.
Fizzy water is soda. They are both carbonated water which is water with carbon dioxide dissolved in it.
An aqueous solution contain a solute dissolved in water.

Sparkling water only needs to contain dissolved carbon dioxide in order to be sparkling. Thus, water with dissolved carbon dioxide but not dissolved sodium ions may be considered sodium free sparkling water.
The water into which carbon-dioxide gas has been dissolved under pressure, is called soda water.
