Why EDTA is soluble in water?

The carboxyl groups of EDTA are not dissociated at low pH. Undissociated carboxyls (COOH) have no charge because the hydrogen is covalently bound and therefore acid EDTA is almost insoluble in water. Dissociated EDTA is ionic and thus water soluble.

Is EDTA oil soluble?

It is miscible in alcohol and propylene glycol, soluble in fixed oils, mineral oil, and alcohol, and sparingly soluble in water. It is obtained by chemical synthesis.

Is EDTA solid or liquid?

Ethylenediaminetetraacetic acid (EDTA) is an aminopolycarboxylic acid with the formula [CH2N(CH2CO2H)2]2. This white, water-soluble solid is widely used to bind to iron and calcium ions. It binds these ions as a hexadentate (“six-toothed”) chelating agent.

Is EDTA a strong acid?

EDTA is a Weak Acid In addition to its properties as a ligand, EDTA is also a weak acid. The fully protonated form of EDTA, H 6 Y 2+, is a hexaprotic weak acid with successive p Ka values of The first four values are for the carboxylic acid protons and the last two values are for the ammonium protons.

How to dissolve EDTA in water?

You can dissolve the acid in water by following a few steps. Mix the EDTA in with about 80 mL of distilled water. Add the NaOH pellets , which should bring the pH of the water up to 8.0, the necessary level to dissolve EDTA. Mix the solution vigorously with the magnetic stirrer until the EDTA dissolves.

What is the chemical formula for EDTA?

The formula of the chemical compound Ethylenediaminetetraacetic acid is C10H16N2O8

What is EDTA mean?

Definition of EDTA. : a white crystalline acid C 10H 16N 2O 8 that is widely used as a chelating and sequestering (see sequester entry 1 sense 3) agent especially to inhibit the reactivity of metal ions. Note: In addition to industrial and scientific applications, EDTA is used as a food additive to preserve foods and inhibit discoloration.
