Alfred Werner published his theory of coordination chemistry in 1893.One of the postulates of his theory was that coordination complexes have "primary valences" and "secondary valences." He showed this by testing the ____ of solutions containing [Co(NH₃)₆]Cl₃ vs.[Co(NH₃)₅ Cl]Cl₂ vs.[Co(NH₃)₄ Cl₂]Cl.

Question
