I am trying to find out what this means..............
99.0 wt% as Na4EDTA•4H2O
83.2 wt% as Na4EDTA
64.0 wt% as H4EDTA
Na4EDTA = also known as Tetrasodium EDTA
H4EDTA = Ethylenediaminetetraacetic acid
4h20 is water content I believe.
I want to mix them together!!!!!
The part I don't understand is the% of each????
83+64=147%
tetrasodium salt of ethylenediaminetetraacetic acid.
Na4EDTA
is the strongest, most versatile, and widely used chelant for controlling metal ions over a broad pH range in aqueous systems.
It will not chelate monovalent metal ions such as
sodium or potassium, but will chelate most multivalent metal
ions (e.g., Fe, Cu, Mn, Ca, Mg, Zn) in a 1:1 molar ratio.
The chelation reaction is virtually instantaneous in most cases.
Calcium and other alkaline earth metals are most effectively
chelated above pH 4.
Na4EDTA chelates most transitionmetals below pH 12.
Someone please explain 1-1 molar ratio
