Question 2 Ratio of COD to Total Organic Carbon (TOC) The generic formula for calculating the ratio of COD to TOC for a given organic compound is given below: Ratio COD / TOC=8(4n+a−2b−3d)(12n)=83+2(a−2b−3d)(3n) a) Explain how the formula is derived b) Calculate the ratio of COD/TOC for the following and comment on the trend: Formic acid (CH2O2 ) Glucose (C6H12O6) Benzene (C6H6) Acetone (C3H6O) Methanol (CH4O) Methane (CH4)
