Is there oxygen in the water? How oxygen in water is produced

There is oxygen in the water, of course. Fish and other creatures in the water live by breathing oxygen from the water, but their respiratory organs are different from those of us humans. Fish, for example, generally use their gills to breathe.

There is oxygen in the water because oxygen is slightly soluble in water.

As for the amount of dissolved oxygen in water, it depends on the situation:

1.Decreases with increasing temperature (so fish should not be raised with water that was once boiled)2The greater the pressure, the more it dissolves (the air pressure is low before the rain.)

So the fish will float their heads)

3.The more plants in the water, the more oxygen there is because the plants can photosynthesize.

Release oxygen. 4.The larger the contact surface with the air, the more oxygen is contained in the water (the pond oxygenator uses this principle.

I would like to make it clear that water is ionized into hydroxide ions.

and oxygen ions, but it has nothing to do with whether the water contains oxygen or not, because these are oxygen ions, which are different from the nature of the oxygen molecules that sustain respiration.

When we talk about air, it is about 20% oxygen, about 80% nitrogen, and a very small amount of other gases.

From the above definition of air, there is no air in water.

But water dissolves or absorbs gases from the atmosphere, including oxygen, nitrogen, carbon dioxide, argon, helium, and so on. In some water bodies enriched with organic matter, reducing agent gases such as methane, hydrogen, and hydrogen sulfide are often present.

At 0, each liter of water contains:

Hydrogen liters, oxygen liters, carbon dioxide liters;

At 20 hours, each liter of water contains:

Hydrogen liters, oxygen liters, carbon dioxide liters;

Many animals, such as fish in the water, breathe in the water through their gills.

Oxygen in water is produced by photosynthesis by plants in the water.

There are two ways in which oxygen is produced in <> water:

1. Dissolved oxygen

That is, the oxygen in the air enters the water, and the amount of dissolved oxygen in the water is an indicator to measure the self-purification ability of the water body. Dissolved oxygen is directly related to the temperature of the water, and the higher the content of dissolved oxygen in the water.

2. Photosynthesis of bacteria and algae.

Some bacteria and algae in water bodies are able to produce oxygen through photosynthesis and release it into the water.

<> scientists have tested that the oxygen content in water is much lower than that in the air. The oxygen content in the air is 18%, and the oxygen content in the water is 6 1000000, which shows that the dissolved oxygen content of water is quite low.

How does oxygen come from in the water? From two sides:

1. It is a plant in water. Photosynthesis is formed by these aquatic plants due to sunlight exposure.

Enables plants to absorb carbon dioxide.

Oxygen is released. 60% of the oxygen in the water comes from aquatic plants;

2. It is supplemented by the atmosphere. at atmospheric pressure.

Under the action, the oxygen in the air penetrates into the water. When the oxygen concentration of the water reaches a saturated state, the water will also release more oxygen into the air. The intensity of sunlight, the size of air pressure, and the temperature will affect the amount of dissolved oxygen in the water.

The higher the water temperature, the solubility of oxygen.

The lower it is, the amount of dissolved oxygen in the water is constantly changing. Changes in the amount of dissolved oxygen can affect the living conditions of the fish.

If there is oxygen in the water, it is dissolved oxygen to shoot socks, not because the water flow is large.

The molecular oxygen in the air dissolved in water is called dissolved oxygen, and the content of dissolved oxygen in water is closely related to the partial pressure of oxygen in the air and the temperature of the water. Under natural conditions, the oxygen content in the air does not change much, so the water temperature is the main factor, and the lower the water temperature, the higher the dissolved oxygen content in the water.

The molecular oxygen dissolved in water is called dissolved oxygen and is usually denoted as do, expressed in milligrams of oxygen per liter of water. The amount of dissolved oxygen in water is an indicator of the self-purification ability of the water body.

The air contains oxygen, and the air is ubiquitous, although it is not easy to dissolve in water, but the water is also the Zen Void of air (Yufu also has oxygen), and the size of the water flow has nothing to do with the size of the water flow, the water flow is larger, contains a little more oxygen, and the water flow is smaller, and the oxygen is slightly less.

There is oxygen in the rivers and lakes, as long as there are fish and micro-cosmetics in the water, the capital hall guesses that there will be oxygen.

Oxygen is a colorless and odorless gas that is slightly denser than air and is not easily soluble in water. 30 ml of oxygen can be dissolved in 1000ml. The solubility of oxygen is affected by temperature and pressure.

The higher the temperature, the less soluble the oxygen, and the greater the pressure, the greater the solubility of the oxygen stool. So there is oxygen in the water, otherwise how can the creatures in the chain cover survive in the water? Coarse.

Because oxygen is soluble in water, there is oxygen in the water. The amount of oxygen in the water is not related to the size of the water flow, but to the temperature and pressure of the water.

The oxygen in the water has a certain solubility, which is relatively small, of course, it is related to environmental conditions such as air temperature and atmospheric pressure.

Why is there oxygen in the water, is it because the water flow is too big, there is oxygen, it is not like that, and the water with oxygen is another kind of object.

Yes. Oxygen is not easily soluble in water, about 30ml of oxygen is dissolved in 1L of water, and the water in the pond is still water when fish are raised, and the oxygen content is not enough to support the daily consumption of fish.

It's okay to circulate the water, but it's not as good as oxygen, because the amount of oxygen dissolved in the water is very small.

The principle of the oxygen pump is to press the air into the water, so that the oxygen in the air is in full contact with the water, so that the oxygen is integrated into the water, so as to increase the amount of dissolved oxygen in the water body, so as to ensure the growth of aerobic organisms.

Because of its convenient and efficient use and low cost, oxygen pumps are widely used in modern fish farming.

1. The oxygen in the water is through photosynthesis.

The production of photosynthesis usually refers to the absorption of light energy by green plants (including algae) and the removal of carbon dioxide.

and water to synthesize energetic organic compounds, and the process of releasing oxygen at the same time. It mainly includes two stages: light reaction and dark reaction, which involves important reaction steps such as light absorption, electron transfer, photosynthetic phosphorylation, and carbon assimilation, which is of great significance for realizing the energy conversion in nature and maintaining the carbon-oxygen balance of the atmosphere.

2. Oxygen, chemical formula O, relative molecular mass.

Colorless and odorless, the body is recited in the air, and the oxygen element.

The most common elemental form. Melting point, boiling point -183 . Not easily soluble in water, about 30ml of oxygen is dissolved in 1L of water.

In the air, oxygen accounts for about 21%. Liquid oxygen is sold as a blue liquid for tomorrow. Oxygenation is a blue crystal.

It is not very active at room temperature, and it is not easy to interact with many substances. However, it is very active at high temperatures and can be directly combined with a variety of elements, which is second only to fluorine in electronegativity with oxygen atoms.

Boiling water contains almost no oxygen.

For example, if you raise a goldfish in a cool white boil, it will die soon after. During the heating process, most of the oxygen in the water is volatilized, so there is very little oxygen in the boiling water.

Oxygen. The water in it is cool, purified, or distilled.

When the oxygen is turned on, bubbles can be seen in the oxygen humidification bottle, and the patient is inhaled by the oxygen that has been filtered and humidified by water. The oxygen cylinder is a high-pressure container for storing and transporting oxygen, which is generally made of alloy structural steel hot stamping and pressing, with an outer diameter of 219mm, and a commonly used gas cylinder volume of 40 liters, cylindrical. It is used in hospitals, first aid stations, and nursing homes.

Oxygen is oxygen, oxygen is one substance, water is another substance, there is no water in oxygen, you want to say air, the air is called water vapor.

It should be that the water evaporated from rain, lakes, rivers, and seas is water vapor.
