You are correct. I think when I made this, I was thinking about biological pH, in which case the amines are protonated, but yes, if the cation (e.g., Ca++) concentration is high enough, there will be a significant amount of EDTA bound in a hexadentate manner.
No, chemical reactivity is the same. Its still amine. What makes complex more stable is that when you have monodentate and it gets decoordinated is simply difunds out. Bidentate, when only one donor is decoordinated cant difund too far because its chain holds it at place. Reactivity is from Thermodynamics but chelate effect is kinetics
Not really, it just a more beneficial reaction since its entropy driven (remember gibbs). Since there are less free molecules coordinated to a single metal, you gain overall freedom in the system as a whole
Entropy is basically a measure of ‘freedom’ of a thermodynamic system. Because you have more Species floating free in the system you have more freedom so greater entropy
This was VERY helpful. My text book was just being ridiculously complicated- sounding like it was giving me degree in Literature and not Chemistry
Not all superheroes wear capes
Actually it’s a flexidentate ligand but mostly it’s supposed to be hexadentate but it might act as tetradentate pentadentate etc
EDTA is HEXA not TETRA dentate :) it forms a deformed octahedric coordination mostly.

@@CatalystUniversity is this English written above??
@@bionicpenguin5471 well yes but actually no
@@CatalystUniversity then if the video is incorrect, re-do it and remove this video.

Your vedios are awesome sir.. The word' OK' you used at the middle of the explanation awesome. I like it. I am fan of your lectures. Thank you sir.
Fantastic video! Thank you!!
Thank you ❤️
EDTA is hexadentate ligand.
Vartika Narula Both hexadentate and tetradentate depending on conditions
@@avishekdutta3310 will citric acid chelate metal hydroxides
Nice video
Bless you
Thank you!
Will a mercury chelator work as an aluminum chelator too? Do different groups of elements need different chelators?
EDTA is hexadentate and can be used tot treat heavy metal poisoning
like pb
Still a freshman yet even I know EDTA, or as you write it (edta), is hexadentate and not tetradentate...
it is both haxa and tetra....depending on the type of edta chosen
Yes many ligands adjust there denticity
EDTA is hexadentate or tetradentate?
Catalyst University. Thanks!!!
Hexa
EDTA is hexadentate
thanks man so chelation makes the complexe less chemically reactive

Shouldn't the entropy decrease because less no. of ligands are getting attached? Just a silly question
entropy of the complex is lowered by the process but overall entropy of the universe increases, so it is a spontaneous process
Entropy is basically a measure of ‘freedom’ of a thermodynamic system. Because you have more Species floating free in the system you have more freedom so greater entropy
Hi,help me with the preparation methods of manganese methionine chelates wet process?
Hi will adding citric acid to metal bases cause them tom be chelated through neutralization or will they still not be chelated
Explain the reality about chelate
