B)ethylenediamine

D)carbonate ion
E)triphosphate ion

Question

Quizplus · Accepted Answer

Chelating agents are molecules that are capable of binding to metal ions through multiple coordinating atoms, creating a stable ring-like structure (chelate). Ethylenediamine, ortho-phenanthroline, carbonate ion, and triphosphate ion all have multiple coordinating atoms and can form chelates with metal ions. Water, on the other hand, has only one coordinating atom (oxygen) and cannot form chelates. Therefore, A) water is not a chelating agent.
