| Abstract: | The experimental teaching, with reference to "Analytical Chemistry Experiment" 1](here in after re-ferred to as "materials" ) method described in the preparation of the Mg2+ -EDTA standard solution in place of the deposition process, with access to similar literature 2-4] , there is no knowledge of the introduction. In this paper, this problem and proposed solution to avoid this omission caused by the teaching and practice of the wrong test re-suits. |
