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.
How do you calculate dissolved oxygen in water?
Dissolved oxygen in water can be calculated using the formula: DO (mg/L) (Volume of titrant x Normality of titrant x 8 x 1000) / Volume of sample (mL). This formula involves titrating a water sample with a reagent to determine the amount of dissolved oxygen present.
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.
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.
What is the relationship between dissolved oxygen and pH levels in water?
The relationship between dissolved oxygen and pH levels in water is that higher pH levels can decrease the amount of dissolved oxygen in water. This is because as pH levels increase, the solubility of oxygen in water decreases. Conversely, lower pH levels can increase the amount of dissolved oxygen in water. pH levels outside of the optimal range can negatively impact aquatic life that relies on dissolved oxygen for survival.
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.

Can a wriggler breathe in dissolved oxygen?
Dissolved oxygen (DO) is the amount of oxygen that is present in the water. Worms, fish, crabs and other underwater animals use gills to get oxygen from the water. Scientists generally agree that the underwater creatures need dissolved oxygen concentrations of 5.0 mg/L or more to live and thrive
What's dissolved oxygen?
Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.

What is mean chemical oxygen demand-?
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
What is the relationship between dissolved oxygen and pH levels in water?
The relationship between dissolved oxygen and pH levels in water is that higher pH levels can decrease the amount of dissolved oxygen in water. This is because as pH levels increase, the solubility of oxygen in water decreases. Conversely, lower pH levels can increase the amount of dissolved oxygen in water. pH levels outside of the optimal range can negatively impact aquatic life that relies on dissolved oxygen for survival.
What is the oxygen dissolved in water is a?
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
In BOD testing what is residual DO?
Residual dissolved oxygen (DO) is the amount of oxygen remaining in a water sample after a specific time period during biochemical oxygen demand (BOD) testing. It is used to calculate the oxygen depleted by organic matter present in the sample, which helps in assessing the water quality and pollution 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.
