Gaseous oxygen does not react with water. 0 $\begingroup$ I know that $\ce{CO_2}$ and $\ce{O_2}$ are slightly soluble in water ($\ce{H_2O}$) In my understanding, when carbon dioxide dissolves in water, it will react to form carbonic acid just like the equation below. Active 5 years, 5 months ago. The mass (weight) of each extra O2 (oxygen) molecule in a liter of water can be added together to get the resulting measurement of DO. Dissolved oxygen is vital to life but how does it get there. Viewed 738 times 1. Higher the temperature, lower the solubility of oxygen. Ask Question Asked 5 years, 11 months ago. Dissolved oxygen in water makes aquatic life possible. Oxygen as well as other gases dissolves in water and its solubility depends on water temperature. Freshwater can hold more dissolved oxygen than saltwater because saltwater has less space for oxygen molecules due to the sodium and chloride ions it contains. 1 decade ago. Warm water holds less dissolved oxygen than cold water because the molecules are moving faster than in cold water and thereby allow oxygen to escape from the water. The mixing of surface waters by wind and waves increases the rate at which oxygen from the air can be dissolved or absorbed into the water.read more Do not confuse oxygen atoms with oxygen molecules. Oxygen dissolve in water. It is water soluble and functions as an oxidator: O 2 + 2 H 2 O + 4 e--> 4 OH-Oxygen may oxidize organic matter. But dissolving is a physical process, not a chemical process and involved no chemical changes. Hence to growth and reproduction of aquatic life must have sufficient levels of dissolved oxygen (DO) in the water. There are oxygen atoms in the water molecules, that's why the molecular formula of water is H2O. In what way and in what form does oxygen react with water? Human being takes oxygen from the air with the lungs. Water, as a polar molecule, induces an accumulation of electron density (dipole moment) at one end of non … Relevance? There are oxygen atoms in the water molecules, that's why the molecular formula of water is H2O. Gills work better if the water contains more oxygen. It can be found dissolved in water as O 2 molecules. On the other hand, Fishes take dissolved oxygen through their gills. what ion would the oxygen form to dissolve, O- or O2-? oxygen is a non polar molecule, o2, how would this dissolve in a polar solvent such as water. Lv 4. 8 Answers. DO (dissolved oxygen) is measured in mg/L. Oxygen enters the water through two natural processes: (1) diffusion from the atmosphere and (2) photosynthesis by aquatic plants. Consequently, the oxygen content of seawater is 85.7%. Because of dissolved oxygen, of course. Do not confuse oxygen atoms with oxygen molecules. Answer Save. Why are fish able to live underwater? This is principally a biological process. But dissolving is a physical process, not a chemical process and involved no chemical changes. Favourite answer. When a liter of water (A) is heated, you will soon have more than a liter of water do to normal expansion (B).
