| Abstract: | This paper reserches into the measuring method of the content of HCl in mixture solution of HCl-FeCl3 by acid-base titration method usins the NH4F?(NH4)2C2O4?EDTA?(NH4)3C6H5O7 respectively as the sequestering agent, usins methyl red or methyl orange as the indicator. It proves that the HCl titration can be varaciously done by usins methyl red as the indicator.and NH4F or(NH4)2C2O4 as the sequestering agent. the relative error and the RSD are satisfied. |
