滴定 Titration

(重定向自Titrimetric)
装在滴定管中的溶液(称作滴定剂),是已知浓度的溶液(即标准溶液),而未知浓度的溶液则装在下方的锥形瓶里。
NaOH滴入HCl的滴定曲线,在pH=7附近发生突跃。横轴是NaOH体积,纵轴是pH值。

滴定titration),在分析化学中是一种分析溶液成分的方法。将标准溶液逐滴加入被分析溶液中,用颜色变化、沉淀或电导率变化等来确定反应的终点。

滴定通过两种溶液的定量反应来确定某种溶质的含量。滴定最基本的公式为:

\frac{c_1V_1}{\nu _1} = \frac{c_2V_2}{\nu _2}

其中c为溶液浓度,V为溶液体积,ν为反应方程序中的系数。

Titration, also known as titrimetry, is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand to determine concentration. The volume of titrant reacted is called titration volume.
