All you have to do to find out for yourself is google "EDTA is a scam?" and you'll quickly find an number of web sites with solid evidence(scientific evidence)showing that EDTA nowhere meets the claims by it's pseudo scientists/supposed MDs. :p

Standardizing EDTA in complexometric titration is done to determine its exact molarity or concentration. This is important because the accuracy of the titration results depends on knowing the precise concentration of the EDTA solution being used. By standardizing EDTA, any errors in concentration can be corrected, ensuring accurate and reliable results in the titration process.
Standardizing EDTA refers to determining the exact concentration of the EDTA solution by titrating it against a known concentration of a metal ion solution. This process ensures that the EDTA solution is accurately diluted or concentrated to achieve consistent and reliable results in complexometric titrations.
EDTA
EDTA is considered a secondary standard because its purity needs to be verified by titration with a primary standard solution to determine its exact concentration. This is due to the fact that EDTA is hygroscopic and its concentration can vary due to absorption of moisture from the atmosphere.
To calculate the concentration of EDTA in titration, you can use the formula: Concentration of EDTA (in mol/L) = (Volume of EDTA used in Liters x Normality of EDTA) / Volume of sample in Liters Make sure to substitute the values for the volume of EDTA used, normality of EDTA, and volume of the sample to determine the concentration.
Ok, it's 1.5 mg per mL of Blood, you can reach this concentration by disolving 0.6 mg of EDTA in 10 mL of still water, then you add 100 microLitters (0.1mL) of this 6% EDTA into a glass tube. The next thing you've to do is to dry the test tube so that you'll only have 6 mg of EDTA, enough to anticoagulate exactly 4 mL of fresh complete blood. The final concentration of EDTA in the blood should be into the range of 1.25 to 1.75 mg per mL. I found this in Dacie's Haematology. karlosgb@live.com.mx
EDTA is a chelating agent that binds to metal ions. In titration, EDTA is used to determine the concentration of metal ions in a solution by forming a complex with the metal ion. The endpoint of the titration is identified by a color change indicator or a pH meter, indicating that all metal ions have reacted with EDTA.

Some types of EDTA titration include direct titration, back titration, complexometric titration, and chelatometric titration. These methods are commonly used to determine the concentration of metal ions in a solution by forming stable metal-EDTA complexes.
The molar mass of EDTA is 372.24 g/mol. To calculate the molarity of the stock solution, you need to divide the mass of EDTA used (18.612 g) by its molar mass and then multiply by the dilution factor (50x). Finally, divide this result by the final volume (1 L) to get the final concentration in mol/L.
To prepare 1mM EDTA from 0.1M EDTA, you would dilute the 0.1M EDTA solution 100-fold. This means you would mix 1 volume of 0.1M EDTA with 99 volumes of a solvent (such as water) to reach a final concentration of 1mM EDTA.
The reaction between calcium and EDTA is a complexation reaction in which the EDTA molecule binds to the calcium ion, forming a stable, water-soluble complex. This reaction is used in titrations to determine the concentration of calcium in a sample.
