Since you have experience in the area, would you explain how difficult is
for a hobbist to prepare a chelated iron solution? I know close to nothing
in chemistry, but I have a 1993 catalog ( Sigma chemical company) where a 2%
solution of EDTA disodium salt is available (12 US dollars for 12 ml). I
always wondered if mixing it in some way (without risk of explosions, major
toxic waste spills or mass poisonings) with micronized iron would give a
cheap chelated iron solution.
Is this feasible with the world's worst chemistry set (mine)?
