The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
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)
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.
Not drinking water
They breathe in the chemical water to get 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.

COD = Chemical Oxygen Demand
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.
what is the dissolved oxygen in a packaged drinking water bottle
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.
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 .
No. Oxygen is a chemical element. Water is a chemical compound of hydrogen and oxygen.
There are three OD's used Total Oxygen Demand (TOD), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) They all measure the amount of oxygen that would be required to consume organic material in the water, BOD is the lowest (usually) as it measures demand from microbes eating easily digested organics (sugars etc), COD measures the demand from all other organics (alcohols etc) measured by digesting the material in strong chemical oxidants, and TOD is the total of the two. Oxygen demand is important to know in waste handling as reducing the oxygen in receiving stream can harm fish and other aquatic life.
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.
The chemical symbol for oxygen is "O." The chemical formula for water is "H2O."
