Ions such as [Co(H₂O)₆]³⁺ and [Ag(CN)₂]^- are called ____. A) ligands B) Lewis bases C) chelates D) alloys E) coordination complexes

Question

Quizplus · Accepted Answer

These ions are examples of coordination complexes, which are composed of a central metal ion surrounded by ligands (molecules or ions that donate electrons to the metal ion). The ligands in these examples are H₂O and CN- in the first and second complexes, respectively. Therefore, the best choice is E, coordination complexes.
