| Abstract: | An indirect method for the determination of the titer of potassium ferricyanide used as titrant in the determination of honey, sugar, starch, and etc . based strictly on the principles of chemical reaction and mathe-matical calculation is proposed in this paper. The purity of the potassium ferricyanide is determined by the standard method GB 644-88, and the titer of the potassium ferricyanide is found by substituting the data of its purity into the formula deduced by the author. |
