How To Dissolve EDTA In Water

Ethylenediaminetetraacetic acid, or EDTA, is a colorless acid that the U.S. Food and Drug Administration has approved for treating lead and heavy metal poisoning, as well as hypercalcemia and ventricular arrhythmias. You can dissolve the acid in water by following a few steps.

Step 1

Mix the EDTA in with about 80 mL of distilled water.

Step 2

Add the NaOH pellets, which should bring the pH of the water up to 8.0, the necessary level to dissolve EDTA.

Step 3

Mix the solution vigorously with the magnetic stirrer until the EDTA dissolves.
