The article discussed the changing relation between total alkalinity content and titration equivalence point and changed situation of methyl orange in the different PH value color.
本文讨论了水样中总堿度含量与滴定等当点的变化关系和甲基橙在不同PH值时的颜色变化情况。
The midpoint and equivalence point for carbonic acid are much higher.
碳酸滴定中点和等量点也高得多。
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鑒别等当点。
According to the experiments, it is found that the titration points between the first equivalence point and the second are more accurate.
