Making EDTA solutions - Which form of EDTA salt to use? (Aug/08/2005 )
I know that most protocols call for the disodium salt of EDTA, and the necessary pH adjustment to get the salt to dissolve.
However, when on the Fisher catalog site, I noticed there are a whole bunch of different forms of EDTA with various salts.
Does anyone know if these other forms could be used instead of the disodium salt? Perhaps an acetate, etc?

We use the tetrasodium salt in our lab. Remember, it won't go into solution until you adjust the pH! Tetrasodium seems to work better than the disodium salt as far as getting it into solution.
