The uncertainty of volumetry for the determination of the Ca~(2+) in the salt sample by EDTA was studied such as the uncertainty from the disposition of the standard solution and demarcation of the EDTA solution, the preparation and the analysis process of the sample,the sample uniformity and the examination of duplication, preparation process form the uncertainty of the sample, the standard uncertainty is 0.70% ;the spread uncertainty is 1.40%.
