What would be the COD values for Dish Detergent, Tap Water, Ethanol, and Acetic Acid? The Data below has everything given. That average section of the Table is used to plot the graph. The First graph with COD calibration line is the standard values (20, 50, 100, 150, and 200) vs their average absorbance values.
