盐酸标准滴定溶液浓度的不确定度评定方法

How to Estimate the Uncertainty of the Concentration of Hydrochloric Acid Standard Volumetric Solution

利用两人八平行测试结果,对标准滴定溶液浓度不确定度的来源进行分析和计算,结果表明,其不确定度主要来自称量和滴定,通过重复测定可大幅度减少标准滴定溶液浓度的不确定度.

To analyze and calculate the source of the uncertainty of the concentration of standard volumetric solutions, we took the parallel results of the measuring from two persons and four times for each person. The results show that the uncertainty mainly comes from weighing and titrating and repeated measuring can dramatically reduce the uncertainty of the concentration of standard volumetric solutions.
