摘要
使用双指示剂测定混合碱含量,是根据两个终点所消耗的盐酸的体积计算混合碱中的组分与含量,利用溶液化学计量点时颜色的明显变化,判断其滴定终点,整个操作经济实用,步骤简单快捷,测定结果较为准确,使用较为广泛。
Determination of mixed alkali contents with double indicator method, is based on the hydrochloric acid computation volume at end points to calculate component and content of the mixed base, color obvious change at solution stoichiometric point is used to judge its end point of titration. The entire operation is practical, simple steps, the determination result is accurate.
