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 principle of chemical oxygen demand?
Chemical Oxygen Demand (COD) is a labortory test to give a measure of the amount of reactive organic materials in a sample of water. Like the five day Biochemical Oxygen Demand (BOD5) it demonstrates the amount of organics present by how much oxygen they consume over a period of carefully controlled conditions (the starting and ending oxidant concentrations are measured and the temperature is controlled)
What chemical formula of drinking water?
Tap water is a mixture of water and other ions that are usually added by local municipalities. The water has the chemical formula of H2O.
What is the chemical reaction for dehydration?
Not drinking water
Why do fish die if chemical fertilizers are mixed with water?
They breathe in the chemical water to get oxygen.
Why is there a demand for chemical oxygen?
There is a very large demand for chemical oxygen. Chemical oxygen is very sought after because it can be used to determine when water is contaminated with pollutants.

Waste water cod stand for?
COD = Chemical Oxygen Demand

What is the significance of BOD and COD in water quality management?
Biochemical oxygen demand (BOD) and chemical oxygen demand (COD) both measure the quantity of organic compounds found in water. The makes them significant when is comes to the treatment of water.
How does the temperature of water effect the dissolved oxygen?
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.
What is the different between biochemical oxygen demand and biological oxygen demand?
Oxygen Demand -The amount of oxygen require to oxidize an organic materialBiochemical (Biological) Oxygen Demand (BOD) -The amount of oxygen required to oxidized any organic matter present in the water by microbes present in the water. Usually representin the easily "digestible" organics.Chemical Oxygen Demand (CO) - The amount of oxidants experessed as oxygen required to consume all organics in a water sampleTotal Oxygen Demand (TOD) the sum of COD and BODBiological Oxygen demand is the oxygen required to oxidized only organic matter by micro organisms (it is basically a prototype of actual process happening in treatment plant) while chemical oxygen demand is the oxygen consumed to oxidize all organic and inorganic matter and it employ chemicals to do this process that why it is way more fast then BOD experiment .
Is oxygen a form of water?
No. Oxygen is a chemical element. Water is a chemical compound of hydrogen and oxygen.
What is the sign for oxygen and water?
The chemical symbol for oxygen is "O." The chemical formula for water is "H2O."
Chemical oxygen demand?
Chemical oxygen demand (COD) is a measure of the amount of oxygen required to chemically oxidize organic and inorganic matter in water. It is commonly used as an indicator of water quality and pollution levels in bodies of water. High COD levels indicate higher organic contamination and can lead to depleted oxygen levels, impacting aquatic life.
What is the chemical reaction for dehydration?
Not drinking water
