Scope

This standard specifies the general method for the determination of chloride
content in inorganic chemical products - Potentiometric titration.
This standard applies to test solutions, which have a chloride ion content of 1
mg/L ~ 1500 mg/L. The chloride (calculated as Cl) content in the test solution,
which is used for titration, is 0.01 mg ~ 75 mg. When the concentration of the
silver nitrate standard solution used is less than 0.02 mol/L, the titration shall
be carried out in an ethanol-water solution.
does not interfere with the determination. The ions that form insoluble
precipitates or complexes with Ag+, as well as , etc. interfere with the
determination. For the limit and elimination method, please refer to Appendix D
(informative) and Appendix E (informative).

Summary	This standard specifies: Determination of chloride content of inorganic chemical products General method potentiometric titration. This standard applies to: the chloride ion content of the test solution in 1mg/L-1500mg/L-. Points taken for titration a test solution of chloride (Cl) content of 0. 01mg ~ 75mg, When using standard solution of silver nitrate concentration is less than 0. 02mol/L while, titration should be carried out in an aqueous solution of ethanol. K +, Na +, Ca2 +, Mg2 +, Mn2 +, Pb2 +, Cu2 +, Ba2 +, NO3-, S02-, BO33-, C02-, PO43- not interfere with the determination, with Ag + form insoluble precipitates or complexes ions and MnO4- etc. interfere with the determination, their limited see Appendix D (Tip Appendix) and exclusion method and Appendix E (Tip Appendix).
