Well, dissolved oxygen impacts water quality because if the level of the dissolved oxygen is too low then organisms can die.
_________________________________________________________________
That is okay, but I want to what dissolved oxygen tests for.
------
For the water quality are tested:
- total oxygen demand (TOD)
- biochemical oxygen demand (BOD)
- chemical oxygen demand (COD)
- sometimes, carbonaceous biochemical oxygen demand (CBOD)
For details about the analytical procedures I recommend you to read a book or a collection of analytical methods for water, searching in a library or searching on the internet.

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.
As water temperature increases dissolved oxygen does what?
As water temperature increases, the solubility of oxygen decreases. This means that warmer water holds less dissolved oxygen than cooler water. This can have negative impacts on aquatic life as they rely on oxygen dissolved in water for respiration.
Why does dissolved oxygen decrease with temperature?
Dissolved oxygen decreases with temperature because warmer water holds less oxygen than cooler water. As water temperature rises, the molecules move faster and are less able to hold onto oxygen molecules, causing a decrease in the amount of dissolved oxygen in the water.
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.
What best describes dissolved oxygen and temperature?
Dissolved oxygen is the amount of oxygen present in water, which is essential for aquatic organisms to survive. Temperature affects the solubility of oxygen in water, with colder water holding more dissolved oxygen than warmer water. Therefore, temperature plays a crucial role in determining the availability of oxygen for aquatic life.
What is the relationship between temperature and dissolved oxygen in a lake?
Temperature affects the amount of dissolved oxygen in a lake - warmer water holds less oxygen than cooler water. Generally, as water temperature increases, the solubility of oxygen decreases. This can have implications on aquatic life, as many organisms rely on dissolved oxygen for respiration.
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.
How is temperature related to the levels of dissolved oxygen in a body of water?
Temperature and dissolved oxygen levels in water are inversely related. As water temperature increases, the amount of dissolved oxygen decreases. This is because warmer water holds less oxygen than cooler water. Therefore, higher temperatures can lead to lower oxygen levels in a body of water, which can impact aquatic life.
What is the relationship between dissolved oxygen levels and temperature in aquatic environments?
The relationship between dissolved oxygen levels and temperature in aquatic environments is that as temperature increases, the amount of dissolved oxygen decreases. Warmer water holds less oxygen, while cooler water can hold more oxygen. This can impact the survival of aquatic organisms, as they rely on dissolved oxygen for respiration.
What is oxygen in water called?
Oxygen dissolved in water is typically referred to as dissolved oxygen (DO). The amount of dissolved oxygen is crucial for the survival of aquatic organisms and is influenced by factors such as temperature, pressure, and biological activity.
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.
What do you think is a contributing factor to a fishkill that occurs during summer months that may be traced to temperature effect on solubility of a gas in water?
At high temperature, oxygen is less soluble in water. Fishes need dissolved oxygen in their respiration. A fish kill results when the dissolved oxygen in water is so depleted that the fish cannot survive.
