在质量化学检验中,滴定分析用标准溶液(以下称标准溶液)就是已经准确知道其浓度,并用来进行滴定的溶液。它是用来计算被测物质含量的主要依据之一。标准溶液浓度准确与否对检验结果的正确性起着重要作用。
In the quality of chemical testing, titration of the standard solution (hereinafter referred to as the standard solution) is already know exactly the concentration, and used to titrate the solution. It is used to calculate the content of the test substance is one of the main basis. Accuracy of the standard solution concentration on the correctness of the test results play an important role.
