Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca ...
Calcium disodium EDTA – preservative; Calcium ferrocyanide – anti-caking agent; Calcium formate – preservative; Calcium fumarate – food acid; Calcium gluconate – acidity regulator; Calcium guanylate – flavor enhancer; Calcium hydrogen sulfite – preservative, antioxidant; Calcium hydroxide – mineral salt; Calcium inosinate ...
Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na 4 EDTA. 4H 2 O. The properties of solutions produced from the anhydrous ...
However, in practice EDTA is usually only partially ionized, and thus forms fewer than six coordinate covalent bonds with metal cations. Disodium EDTA is commonly used to standardize aqueous solutions of transition metal cations. Disodium EDTA (often written as Na 2 H 2 Y) only forms four coordinate covalent bonds to metal cations at pH values ...
Sodium calcium edetate (sodium calcium EDTA), also known as edetate calcium disodium among other names, is a medication primarily used to treat lead poisoning, [2] including both short-term and long-term lead poisoning. [3] Sodium calcium edetate came into medical use in the United States in 1953. [3]
