I think free iron is pretty toxic actually. was just trying to explain why some complexes are less reactive than others.
You seemed more like sniper to me.

I must confess as someone who has endured real-life sniper fire more than once, this had the feel.
Apparently, according to ordloh, I am wrong about the need for or use of chelating agents with iron.
If the object was to say, I am wrong in my advice to Aaron, fine, say so.
If the point is to say, I misused or misunderstood the materials I cited, fine as well, quite possibly correct. The last serious chemistry class I took was decades ago. I am reluctant to cite extension classes and audit courses at community colleges, but I am making an effort, however humble it may be, to understand and pass it along.
If the object is to highlight or correct my reasoning but support the advice, also fine. Citations are nice including citing one’s own accomplishments are fine as well.
My experience leads me to advise the use of iron with chelating agents.
My apparent misunderstanding regarding gluconate was that it did not hang around as long as iron chelated with EDTA, which I had until recently believed was good through around pH 10 or so.
On this forum and reading suggested here, I have also come to believe that DTPA may indeed be more stable, especially over pH 7 and more effective for our purposes or at least my purpose.
