Hey, who’s that Yongho? Can’t recognize myself anymore – that’s so scary.
Kuwata: so can anyone explain why our EDTA chelate will only hydrolize four ions and not these (indicates possible inner hydrogen ligands) other two? Would you predict they will hydrolize as the titration is put forward or maybe during a back titration?
Yongho: Well probably it’s because of the intramolecular forces, mainly oxide groups put so close together.. and the increase of ionic radius because of hydrolysis… (bunch of inconvex facts) from which we could predict a complete octahedral chelating effect after the second titration point.
Kuwata: Actually, … you make a good point, but at the conclusion you’re completely wrong.
