Edta is which ligand
Weba ligand that readily forms a complex with the metal ion. Ethylenediaminetetraacetic acid (EDTA) is used to complex the Co2+. EDTA is a polydentate ligand. This means that it can donate more than one pair of nonbonding electrons when forming a complex with a metal ion. In fact, EDTA can form 6 bonds with a metal ion and thus occupy all WebEDTA fulfills most of the conditions for a good complexometric titrant. It forms sufficiently stable complexes with most metal ions (except the alkali metals which form too weak complexes), all the complexes have exact 1:1 stoichiometry (regardless of the charge of the cation), the reaction with most metal ions (except Cr 3 +) is rapid, the complexes are …

One example of a hexadentate ligand that can form … WebWhen a ligand forms complexes with two metal ions at equal concentration in a solution, the ligand will form complexes preferentially with the metal ion that produces the complex with the larger stability constant. Example: EDTA titration of hardness. Ca 2+ + EDTA 4-<----> (EDTA-Ca) 2-: K = 10 +10.7
WebIf the buffer is a ligand that binds to Cd 2+, EDTA has to compete with the ligand for Cd 2+. EDTA as a chelating ligand, it forms a stronger complex with Cd 2+ and will displace NH 3, but the presence of NH 3 decreases the stability of Cd 2+-EDTA cpx.
