Appearance: white solid
Tetrasodium EDTA is a white solid, very soluble in water and forming a basic solution. Prepared from ethylenediamine, formaldehyde, and sodium cyanide in basic solution, or from ethylenediamine and sodium chloroacetate, EDTA is a strong complexing and chelating agent. It reacts with many metallic ions to form soluble chelates. As such, it is widely used in analysis to retain alkaline earths and heavy metals in solution. It is used as an antidote for metal poisoning, an anticoagulant, and an ingredient in a variety of industrial reagents.
USING EDTA TO REJUVENATE LEAD-ACID BATTERIES:
EDTA tetra sodium salt can be used to dissolve and remove sulphate deposits from lead acid batteries. This is not a permanent fix for old batteries but it will extend their life.
For an average sized battery add 5g (1 teaspoon) of EDTA per cell. Dissolve the EDTA in deionised water before adding. Note: Do not try to dissolve EDTA in battery acid. Remove a small amount of acid in cell and add EDTA solution. Allow to sit for a few days, agitating the solution regularly and then fully charge battery.
