How might you account for dissolved oxygen concentrations of such a low value at a temperature of 25C?
Other factors must have caused the low dissolved oxygen levels. Bacteria and other organisms can lower the dissolved oxygen of water when they respire aerobically.
Why does metal not rust in boiled water?
Water at high temperature will have less dissolved gases including oxygen.
What is dissoving?
Dissolved Oxygen is the bubbles in water when you splash there's bubbles in the water that is Dissolved Oxygen.
Importance of dissolved oxygen in water?
oxygen is dissolved in water and is also important for the survival of aquactic animals and plants
As the temperature of an aqueous solution increases what does the concentration of gas dissolved in the solution do?
An aqueous solution has 0.0070 gram of oxygen dissolved in 1000. grams of water. calculate the dissolved oxygen concentration of this solution in parts per million?A. 17ppm B. 27ppm C. 7ppm D. 7ppm
What is the typical limiting factor in streams lake and freshwater environment?
Factors that limit aquatic life are - Temperature - Access to sunlight - Dissolved oxygen concentrations - Availability of nutrients, such as nitrogen and phosphorus
how does temperature affect the concentration of dissolved oxygen?
Temperature has a direct effect on the concentration of dissolved oxygen in water. As the temperature of the water increases, the solubility of oxygen decreases and the concentration of dissolved oxygen will decrease. Conversely, as the temperature of the water decreases, the solubility of oxygen increases and the concentration of dissolved oxygen will increase. Additionally, warmer water is generally less dense than colder water, resulting in less efficient oxygen transfer.
How does saltwater rust nails?
The ion chloride (Cl-) and the oxygen dissolved in water have a corrosive effect,
When water temperature increases what will the dissolved oxygen content do?
The amount of dissolved oxygen decreases when water temperature increases. Warm water is unable to dissolve as much oxygen gas.
Do trout need saltwater or freshwater to survive?
Trout are fresh, cold water fish that need high oxygen levels.
Which contain the greater amount of dissolved oxygen a lake in the spring or a lake in the summer?
. Temperature directly affects the solubility of oxygen in water. When the temperature of water increases, a portion of oxygen converts from liquid state to a gas. Thus the ability of water to maintain oxygen in dissolved state decreases with increasing temperature. As a result, colder water can potentially contain more dissolved oxygen than warm water. Therefore, a lake in spring contains greater amount of Dissolved Oxygen than the same lake in summer.
Why does dissolved oxygen change when the water temperature goes up?
Because it does.
Can tangs be kept in a freshwater aquarium?
No, Tangs cannot be kept in fresh water. Tangs are a saltwater fish. The way I had it explained to me is that saltwater fish don't have enough salt in their bodies, so they have to live in saltwater to make up the extra, and visa versa. Putting a Tang in freshwater would be like putting you on Mars without oxygen.
Where would you expect to find the largest amounts of dissolved oxygen in the ocean water?
Oxygen best dissolves at surfaces. So generally, you would find the largest amount of dissolved water at the surface, which is in contact with the air. As for a region, I would assume a region that has a lot of photosynthetic organisms and not a lot of oxygen consumers. Another factor that should be kept in mind, is that the lower the concentration of solutes (i.e.. salt) in the water, the more oxygen can be dissolved. For example, at 10 degrees Celsius, up to 8.02mL of oxygen can be present per liter of freshwater, but only 6.75mL of oxygen is dissolved per liter of saltwater. ______________ In polar regions.

How different plants and animals survive in water?
Aquatic animals and plants have evolved significant salt balance conservation systems, ensuring that either the freshwater they live in doesn't leech into their cells or that the saltwater they live in doesn't leech the water out of their cells. They have also adapted to absorbing dissolved oxygen from the water.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
