What is dissolve oxygen?
Dissolved oxygen refers to the amount of oxygen present in water. It is essential for aquatic life to breathe and thrive. Factors such as temperature, water flow, and levels of organic matter can impact the amount of dissolved oxygen in water.
What does the level of dissolved oxygen go down after sunset?
The level of dissolved oxygen in water can decrease after sunset due to the lack of photosynthesis by aquatic plants. Without sunlight, plants stop producing oxygen through photosynthesis, while organisms in the water continue to consume oxygen through respiration, leading to a decrease in dissolved oxygen levels.
What can decrease the amount of dissolved oxygen in water?
Sometimes, water can become overheated, like if it is near a factory or power plant. If the water's temperature increases, then the Dissolved Oxygen (DO) level will decrease, which can cause strain or even death for many fish and marine wildlife.
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.

Is oxygen a solute?
no
How does pH affect the levels of dissolved oxygen in a solution?
The pH level of a solution can affect the levels of dissolved oxygen. When the pH is lower (more acidic), the solubility of oxygen decreases, leading to lower levels of dissolved oxygen. Conversely, when the pH is higher (more basic), the solubility of oxygen increases, resulting in higher levels of dissolved oxygen.
What changes the amount of dissolved oxygen in the water?
Factors such as temperature, pressure, salinity, and the presence of organisms can affect the amount of dissolved oxygen in water. For example, higher temperatures typically result in lower dissolved oxygen levels, while photosynthesis by aquatic plants can increase dissolved oxygen through oxygen production.
how does water turbidity affect dissolved oxygen?
Ask someone smart.
Normal ranges for dissolved oxygen test?
dissolved oxygen is dissolved oxygen
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
What is true of dissolved oxygen in water?
Dissolved oxygen in water is essential for aquatic organisms to survive and thrive. It is crucial for the respiration of fish and other marine animals. Factors such as temperature, water depth, and plant life can affect the levels of dissolved oxygen in water.
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.
Does water temperature affect oxygen?
Yes, water temperature affects the amount of dissolved oxygen it can hold. Colder water can hold more oxygen than warmer water. This is important for aquatic organisms that rely on dissolved oxygen for respiration.
Does tin cans will not affect the amount of dissolved oxygen in water?
Tin cans themselves do not affect the amount of dissolved oxygen in water. However, if tin cans are oxidized or corroded, they may release metals into the water that could potentially impact oxygen levels and water quality. Proper disposal of tin cans is important to prevent any negative effects on water quality.
How does algae growth affect dissolved oxygen levels?
Algae growth can lead to fluctuations in dissolved oxygen levels in water bodies. During daylight hours, algae photosynthesize and release oxygen, increasing dissolved oxygen levels. However, at night or when algae die and decay, they consume oxygen through the process of decomposition, which can lead to a decrease in dissolved oxygen levels, potentially creating hypoxic conditions for aquatic organisms.
What are some factors that can affect Dissolved Oxygen?
Temperature: Lower temperatures generally result in higher dissolved oxygen levels. Salinity: Freshwater holds more oxygen than saltwater. Turbulence: Mixing and aeration from water movement can increase dissolved oxygen levels. Organic matter: Decomposition of organic matter by bacteria can deplete oxygen levels.
What is the definition of dissolved oxygen?
No, you can't dissolve oxygen in water, even if it's under the ocean. However, hydrogen and oxygen can be generated by passing an electric current through water and collecting the two gases as they bubble off.
