Hello, I just bought an EDTA for oral chelation. As I live in a very poor country, I bought the pure EDTA from the local chemistry shop - highly acidic. In the chelation therapy the salts of EDTA are used, usually disodium or calcium-disodium.
Now I have two solutions:
1. I can simply make the tetrasodium, using the sodium bicarbonate - or even disodium, if I remember correctly chemistry class, using the precise weighing scale and calculating numbers from molar mass.
2. I can use the acidic EDTA directly as chelating agent.
Now, questions:
1. I'm not sure if this chemistry reaction will work, I'm not really experienced with chelating agents. I was able to create my own calcium citrate (using the citric acid and calcium carbonate), strontium citrate (same way), neutral salt of vitamin C which doesn't cause any stomach pain, is safe for enamel and works just like the normal one (sodium bicarbonate vs ascorbic acid), I'm 99% positive tetrasodium EDTA will work just like disodium, as the chelating agent just exchange sodium ions with heavy metal ions (this is how calcium disodium EDTA works, it's not acidic and still is able to remove lead from body). Anyone can correct me?
2. Is acidic EDTA safe? It's not the really strong acid, way softer than the vitamin C or apple cider vinegar, and acid toxicity comes from it's acidity and ion it create during reaction - while acidity is pretty safe in this case, ions are just EDTA salts commonly used. Still, as I'm not really experienced with the chelating agents, I can't say it's 100% true.
Anyone can help me?
ps. sorry for my English, it's not my 1st, not even 2nd language.
