pH 10에서 EDTA의 구조

What is the structure of EDTA at pH 10?

 

---------------------------------------------------

 

At pH 10, ethylenediaminetetraacetic acid (EDTA) exists in its fully deprotonated form, meaning that all of its acidic protons are dissociated.

 

The structure of EDTA at pH 10 is a highly charged anion with a complex of four carboxylate groups and two nitrogen atoms that can bind to metal ions.
