Endpoint and Indicator for the Determination of Alkalinity of Water

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值下颜色的变化情况。试验了可用于滴定水样总碱度的常见的10种酸碱指示剂。结果表明,用溴甲酚绿指示终点优越,颜色突跃清楚。

Abstract: A discussion is given of the relation between the alkalinity and titration equivalence point, and of the color change of the methyl orange indicator with different pH values. Ten indicators were tested for alkalinity determination and it was found that br
