EDTA Di Sodium Salt

The Disodium salt of EDTA is the most commonly used form of this versatile organic complexing agent.
Part number
RXSOL-42-6168-025
Brand

RXSOL

Overview

EDTA is the commonly used abbreviation for (Ethylene­dinitrilo)­ tetra­acetic Acid (also called Ethylene­diamine­tetra­acetic Acid or Edetic Acid).

Technical specifications

EDTA is most commonly used to determine hardness (i.e., Calcium and Magnesium ions) in water, where the pH must be approximately 10 and is usually controlled by adding a buffer such as Water Hardness Buffer. Water Hardness Indicator (Eriochrome Black T), Eriochrome Blue Black R, Calmagite, and Murexide are used for hardness or Calcium determinations using EDTA.

Applications

The Disodium salt of EDTA is the most commonly used form of this versatile organic complexing agent, which is used for the determination of many metal ions either by direct titration or by back-titration. Adjustment of reaction conditions, either by controlling the pH or by use of masking agents, and selection of the appropriate indicator permits a wide variety of metal ions to be determined using EDTA.

Dosage and directions

Molarity is best used in expressing EDTA concentration, because the reaction involves the complexation of one metal ion by one EDTA molecule or ion, whether the free acid form of EDTA or one of its more soluble Sodium salts is used. The general reaction involving the Disodium salt is:

EDTA2- + Mn+ → [EDTA-M]+n-2
where M = Ca, Mg, Cd, Mn, Ni, Al, Zn, Bi, Co, Cu, or other metal ion

Characteristics and notes

An indicator is added that forms a colored complex with some of the metal ion being determined. When the endpoint is reached, all of the free metal ion has been complexed by the EDTA. The last addition of EDTA then removes the metal ion from its complex with the indicator, producing a color change. The relative strength of the EDTA-metal ion complex compared to that of the indicator-metal ion complex determines whether a direct titration or a back-titration is applicable.

Safety and SDS

Read the safety data sheet before handling. Wear suitable gloves and eye protection.
