Part 2 of the GB/T 6276.2-2010 specifies the potential Titrimetric method for the determination of chlorides in industrial carbonic acid ammonium hydrogen. It is suitable for all kinds of industrial carbonic acid ammonium hydrogen products. The method is based on the change of potential during the reaction of chlorides and titrants to determine the titration endpoint. The standard specifies the requirements of instruments such as Potentiometric titrator, and specifies the preparation and calibration of reagents. Detailed description of Sample Handling steps, including dissolving of carbonic acid ammonium hydrogen samples, elimination of interfering substances, etc. Standardized titration operation procedures, such as titrant addition speed, potentiometric monitoring Frequency and endpoint judgment basis. According to this standard, the chlorides content can be accurately determined to help control the mass of industrial carbonic acid ammonium hydrogen products.
