GB/T 3050-2000 provides a general potential Titrimetric method for the determination of chlorides content in inorganic chemical products. It is suitable for all kinds of inorganic chemical products. The end point is determined by measurement of potential changes during titration, and then the chlorides content is determined. The standard specifies the required instruments, such as Potentiometric titrators, electrodes, etc., and specifies the requirements of reagents. Detailed description of Sample Handling steps, including dissolving, adjusting pH value, etc., as well as titration operation procedures, such as titrant addition speed, potential measurement timing. The standard unifies the determination method to ensure accurate determination of chlorides content in inorganic chemical products, providing key data support for product mass control, performance evaluation and production process optimization.
