WebAs a result, COD values are greater than BOD. In comparison with BOD 5, COD measurement has an advantage in that it requires a short digestion period of about 3 hours rather than incubation of 5 days period required for BOD 5 measurement. For many types of wastes, it is possible to correlate COD with BOD. ... As one molecule K 2 Cr 2 O 7 can ... WebCalculations: –. FAS K 2 Cr 2 O 7. N 1 V 1 = N 2 V 2. Where N 1 = Normality of FAS. V 1 = Volume of FAS used for titration of Dichromate. N 2 = Normality of Potassium Dichromate. V 2 = Volume of Potassium Dichromate taken for titration. By putting the above values the Normality of FAS can be calculated. Precision & Bias: For COD of 200mg/lit ...
