摘要
本文讨论了水样中总碱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。试验了可用于滴定水样总碱度的常见10种酸碱指示剂。结果表明,用溴甲酚绿指示剂终点优越,颜色突跃清楚。
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. Ittried the common 10 kinds of acid - base indicators which are available in the titration water sample total alkalinity. The result indicated that the end point of bromocresol green indicator is advantageous and shows clearly color.
