The correct formula of triamminediaquachlorocobalt (III)iodide is ________. A)[Co(NH₃)₂(H₂O)₃Cl]I₂ B)[Co(NH₃)₃(H₂O)₂Cl]I₃ C)[Co(NH₃)₃(H₂O)₂Cl]I₂ D)[Co(NH₃)₃(H₂O)₂Cl]I E)[Co(NH₃)₃(H₂O)₂I]Cl₂

Question

Quizplus · Accepted Answer

The prefix "tri" indicates three, meaning there are three ammonia molecules present. The suffix "-aqua" indicates that two water molecules are present. The complex ion has a negative charge, which is balanced by the iodide ion (I-). The oxidation state of cobalt (III) is indicated by the Roman numeral III in parentheses in the name, which means it has a charge of +3. The presence of one chloro ligand is also indicated in the name. The correct formula can be written as [Co(NH3)3(H2O)2Cl]I. Choice C is the only option that matches this formula.
