The amount of oxygen used by the suitable microorganisms present in water during five days at 20^(@)C is called as BOD. For pure water BOD is about 1 ppm fairly pure water 3 ppm and doubtful purity 5 ppm the municipal sewage has BOD values 100-4000 ppm. BOD= Number of moles of O_2 required / Number of liters of water sample The BOD values of three water sample x,y and z are 5 mg/litre, 16 mg/Litre and 400 mg/Litre respectively the more polluted sample of water is
