变色范围 meaning in Chinese
color change interval
range of color change
Examples
- Color range of indicator
指示剂变色范围 - The effect of surfactant micelles on the dissociation constants and the colour - changing points and ranges of acid - base indicators
胶束对酸碱指示剂离解平衡和变色点及变色范围的影响 - The experimental results indicated that the colour - changing ranges got narrow , and the titration accuracy was increased when an appropriate surfactant micellar solution was chosen as a titration medium
实验结果表明，表面活性剂存在时，酸碱指示剂的离解平衡及其变色范围将发生改变，选择适当的胶束溶液作为滴定介质，可以扩大酸碱指示剂的应用范围，同时也可以提高滴定的准确度。 - The effect of hexadecy pyridine choride on the dissociation constants of thymol blue bromide , cresol red , o - ckesolphthalein and thymol blue , as well as their the colour - changing ranges were studied by spectrophotometry
探讨了表面活性剂氯化十六烷基吡啶形成的胶束对溴百里香酚蓝、甲酚红、邻甲苯酚酞和百里香酚蓝离解反应的离解常数的影响，同时，也研究了该表面活性剂对上述四种酸碱指示剂变色范围的影响。 - The effect of hexadecy pyridine choride on the dissociation constants of thymol blue bromide , cresol red , o - ckesolphthalein and thymol blue , as well as their the colour - changing ranges were studied by spectrophotometry
