raivo Posted January 25, 2005 Posted January 25, 2005 Can anyone explain how EDTA is used for titration? I read somewhere that EDTA reacts with metal ions and color of erichrome black indicator changes when there is no free EDTA any more. Right? Are there other indicators that can be used for titration with EDTA? Is there way to tell by such titration what metal ions those were that reacted with EDTA?
budullewraagh Posted January 25, 2005 Posted January 25, 2005 ethylenediaminetetraacetic acid is indeed an acid. thus, it can be used in titrations for alkaline solutions

Dhawal Posted January 26, 2005 Posted January 26, 2005 EDTA has 4 acidic H that make it a reasonably good strong acid
budullewraagh Posted January 26, 2005 Posted January 26, 2005 the dissociation constant isnt exactly low.....
