EDTA has a number of chemical properties, including an attraction for heavy metal ions with which it readily binds. It is this property that recommends it for use as a chelating agent, a class of chemical compounds that are supposed to do just that. However, the value of this "therapy" is questionable, and EDTA has other properties that may make it dangerous in high doses.
It's also used as a buffer for acid/base titrations, if I recall my quantitative analysis.

Stoichiometry, EDTA, Phenolphthalein, micro-gram scales. That's been a while.
EDTA is in a lot of stuff.
