Tetrapotassium EDTA is a chelating agent and sequestering agent used in a wide range of applications. It is a white, free-flowing, crystalline powder that is soluble in water and other polar solvents. It has a high affinity for metal ions and binds them to form a stable, water-soluble complex. This makes it ideal for removing heavy metals from aqueous solutions, sequestering metal ions from soil, or stabilizing metal-containing formulations. It is also used in detergents, cleaners, and other industrial applications.
