List Of Chemical Oxygen Demand Questions And Answers Ideas. Generally, a silver compound is added as a catalyst to promote the oxidation of certain classes of organics, and a mercuric compound may be added to. For samples from a specific source, cod can be related empirically to bod, organic carbon, or organic matter.
Chemical oxygen demand (cod) is measured through the reaction of organic compounds with potassium dichromate forming chromium (iii) ion. A) much higher b) zero c) much lower d) low answer. Ask your doubt of chemical oxygen demand (cod) and get answer from subject experts and students on topperlearning.
Chemical Oxygen Demand Is The Necessary Oxygen To Be Used In Water Chemical Reactions (Oxidation.
Amount of oxygen that would be removed from the water in order to oxidize pollution, 2. They also do not like web links. Lakes and rivers) or wastewater, making cod a useful measure of water quality.
The Chemical Oxygen Demand (Cod) Test Uses A Strong Chemical Oxidant In An Acid Solution And Heat To Oxidize Organic Carbon To Co 2 And H 2 O.
So below is the answer to your question and if websites are appropriate, you will need to do the searches yourself based on the information in the a. How is the value of cod compared to bod? It provides an index to assess the effect that the discharged wastewater will have on the receiving environment.
The Computation Of Cod Is In The Following:
Cod = chemical oxygen demand, mg/l a = amount of ferrous ammonium sulphate titrant added to blank, ml b =. Amount of oxygen required to oxidize the calcium present in waste water , 5. The dichromate chemical oxygen demand (cod) test measures the oxygen equivalent of theamount of organic matter oxidizable by potassium dichromate in a 50% sulfuric acid solution.
Amount Of Oxygen Required To Oxidize The Calcium Present In Waste Water , 5.
Amount of oxygen required for growth of microorganisms in water, 3.none of the above, 4. The chemical oxygen demand (cod) test is commonly used to indirectly measure the amount of organic compounds in water. As the waste amount increases, it requires more oxygen for its decomposition.
The Chemical Oxygen Demand (Cod)Measures The , Options Is :
The chemical oxygen demand (cod)measures the , options is : Chemical oxygen demand (cod) is defined as “a measure of the oxygen equivalent of the organic matter content of a sample that is susceptible to oxidation by a strong chemical oxidant.*”. Chemical oxygen demand (cod) is the measure of the amount of oxygen necessary to oxidize all the pollutants present in water.
