Question
What is the use of solubility of oxygen and carbon dioxide in water?
Solution
Air dissolved in water is biologically very important.
- Oxygen dissolved in water is used by marine life like fish for respiration, and thus, marine life is sustained.
- Aquatic plants make use of dissolved carbon dioxide in photosynthesis to prepare food.
- Carbon dioxide dissolved in water reacts with calcium carbonate to form calcium bicarbonate.
Marine organisms such as oysters and snails extract calcium carbonate from calcium bicarbonate to build their shells.
