In environmental chemistry, the chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution.It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre (mg/L).A COD test can be used to easily quantify the amount of organics in water. The basis for the COD test is that nearly all organic compounds can be fully oxidized to carbon dioxide with a strong oxidizing agent under acidic conditions. Relating to both physical and chemical properties. 2. a. The internationally dominant method today is the so-called 'Dichromate' method [5][6] which is characterized by the acidification of the sample with sulphuric acid and the addition of silver sulphate. In chemistry, the standard conditions are defined as: a specified temperature; 1 atm pressure; 1 mol dm −3 concentration; To indicate that a quantity was measured under standard conditions, a superscript plimsoll line symbol, o, is added to the quantity's symbol.
