 note = {An investigation into the precise crystalline structural report of ethylenediaminetetraacetic acid (EDTA), a representative chelator learned in the education of analytical chemistry, was initiated as there appeared to be apparent ambiguity regarding the accurate notation of EDTA as a neutral molecule or a zwitterion. Consequently, the first and foremost article reporting EDTA as zwitterionic form was determined after a difficult confirmation. Additionally, crystallographic data of the zwitterionic EDTA itself and non-chelated salts thereof registered on the CCDC are also summarized herein. This episodic knowledge will be fundamental for not only chemical education but also related fundamental and applied sciences., EdArXiv, doi: https://doi.org/10.35542/osf.io/n9jf4},
