EDTA Tetrasodium – My Blog

EDTA Tetrasodium

Is also known as Tetrasodium Edetate. It is Tetra Sodium salt of Ethylene diamine tetraacetic acid.

It white solid, very soluble in water and forms a basic solution. Prepared from EDTA acid and Sodium Hydroxide, It is a strong complexing and chelating agent. EDTA Tetrasodium 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 and to dissolve scale.

We are the wholesale & the best leading EDTA Tetrasodium Manufacturers, EDTA Tetrasodium suppliers & traders in India

We can also offer in liquid Form on request.

EDTA Tetrasodium possesses enormous usefulness because of its role as a chelating agent, i.e. its ability to “sequester” metal ions such as Ca2+ and Fe3+. After being bound by EDTA, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA and calcium disodium EDTA.

It is easy to use and is added to emulsions in the water phase at typical use levels of 0.02%-0.1% so it is very cost effective.
