Typically, 1-2 mg of EDTA per milliliter of blood is added for anticoagulation purposes in laboratory samples. The exact quantity may vary depending on the specific laboratory protocol being followed.
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
use heat to heat the solution and add EDTA slowly to dissolve it.

Buffers are added to systems in order to resist any minor changes in pH. EDTA is an acid, (ethylene diamine tetracetic acid), and so a buffer is used in order to maintain a certain pH even after the EDTA is added.
You will be using the disodium salt of EDTA (M.W. = 372.24 g/mole). It has been dried for 1day at 80°C to drive off any superficial moisture. Transfer it in desiccator for an hour.Weigh carefully about 1.95 g of EDTA (record tothe nearest 0.1 mg). Quantitatively transfer this into a 500 mL volumetric flask then add 2-3 mLof pH 10 ammonia buffer. Fill the flask about halfway to the mark with deionized water andswirl to dissolve. This process can take up to 15 minutes. Once dissolved, dilute to the markand then cap and invert the flask at least 6 times to get a uniform solution. Keep the solutioncapped.This solution is about 0.01M but for an exact value you need Standardization of this solution with Calcium Carbonate standard solution.

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
No.
Yes, EDTA is water-soluble. To prepare a solution, you can simply add the desired amount of EDTA powder to water and stir until it is completely dissolved. If you encounter issues with solubility, you can adjust the pH of the solution using sodium hydroxide or hydrochloric acid to help dissolve the EDTA.
EDTA is used in manufacturing to improve emulsification. At home, you yourself can control the rate of addition of oil to protein, so there is no need for you to add EDTA to your homemade mayonnaise. All your mayo needs is oil, egg yolk and a splash of vinegar.
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
Adding a buffer solution before titration with EDTA helps to maintain a constant pH which is crucial for the formation of metal-EDTA complexes. The buffer solution prevents any fluctuations in pH that could affect the accuracy and precision of the titration results.
To perform an EDTA titration, first prepare a solution containing the analyte (the substance being measured) and a suitable indicator, such as Eriochrome Black T. Add a standardized solution of EDTA to the analyte solution until the endpoint is reached, indicated by a color change in the indicator. The volume of EDTA solution added can be used to calculate the concentration of the analyte based on the stoichiometry of the reaction.

When you add zero to any quantity, the sum is the original quantity.
