The equivalence point is identified from the first faint pink color that persists in the solution being titrated.
可从第一次出现在正在被滴定的溶液中的稳定的微红色来鉴别等当点。
2
The excessive EDTA standard solution was titrated using copper sulfate with PAN as indicator so as to obtain nickel content.
以PAN为指示剂用硫酸铜标准溶液滴定过量的EDTA标准溶液，从而求得镍的含量。
3
The calculating analysis of titration without standard solution is a method that can be used to determine the concentration of substance titrated and titrant at the same time.
