| Abstract: | The two-point potentiometric titration was applied to the rapid determination of NH_4Cl in cough syrup. Only two data of the volume of titrant (AgNO_3 standard solution was used as titrant in this method) before and near the estimated stoichiometric point were taken together with the corresponding potential values. The exact stoichiometric point of the titration and the content of NH_4Cl was calculated by the formula given in this paper. |
