Edetic Acid Monosodium Salt, also known as EDTA-Na, is a compound commonly used in various settings, such as food preservation, cosmetics, and chelation therapy. It is a chelating agent that binds to metal ions, reducing their reactivity. Antonyms for Edetic Acid Monosodium Salt could be compounds that increase metal ion reactivity, such as heavy metal salts including lead, copper, and zinc compounds. Another antonym could be non-chelating agents that do not bind to metal ions, such as water, salt, or organic solvents.
