CODCOD— Chemical oxygen demand; AA— Volume of ferrous ammonium sulfate for the blank run; BB— Volume of ferrous ammonium sulfate for the sample; and NN— The normality of ferrous ammonium sulfate. This chemical oxygen demand formula is the basis for the calculations in the COD calculator. ...
The symbols used on the periodic table are based on the Latin name of the elements and are universal, regardless of what language the periodic table is written in. The chemical symbols used on the periodic table are the same as those used in chemical formulas, which lets us determine what...
