滴定分析用标准溶液的实践分析

Analysis about the Practice of Standard Solution Used in Titration

标准溶液是已知其准确浓度的溶液,在滴定分析中用来滴加到被测物质中与被滴定的组分按照化学反应式的计量关系达到理论终点,根据消耗的标准溶液的浓度和体积来计算待测组分的含量,因此标准溶液的准确配制及标定直接影响到分析结果的准确。在实际的生产检测中标准溶液被广泛应用,许多产品的检测都是通过标准溶液来完成的。文章结合生产实际对标准溶液进行分析讨论。

Standard solution is a kind of exactly kwown solution, which will be instilled into unknown material, in which both enter reaction and then attain the theory end point. According to the quantify relation, base standard solution concentration and volume that be wasted to count the quantity of component for measure. So the compound and calibration of standard solution will affect directly the accuracy of analysed result. In this actual production test, the standard solution is widely used, many products are detected by standard solution to complete. Combining with the actual production, the paper analyses and discusses the standard solution.
