It takes a lot of time and still doesnt dissolve.
Why edta dissolves at ph 8. Note that EDTA is tetravalent meaning that it has four carboxylic acids that can be titrated with your sodium hydroxide giving increasing proportions of sodium carboxylate chemical functions by increasing the pH.

Although addition of a few drops of NaOH makes the process a bit easier still takes a lot of time Now it did not make sense to me of why NaOH made EDTA. ESTA is more soluble in water in its salt form like sodium EDTA disodium ESTA trisodium EDTA tetrasodium EDTA than when when it is in its protonated acidic form.
