- Scope
- This standard specifies the content determination method of weighing the standard titration solution or reference solution with a balance and determining the end point by potentiometric titration. The precision of this method is 0.02%, and the total uncertainty is ±0.05%. This standard is applicable to the content determination of the working reference reagent (capacity) with a content of 99.95% to 100.05%. It is especially suitable for the determination of the end point which is difficult to grasp by indicator titration.
