In [Fe(NH₃)5Cl]Cl₂, the 2 Cl− ions outside the coordination sphere are ionizable and form AgCl, while the inner Cl is a ligand. Thus, 2 moles precipitate.

In [Cr(H₂O)5Cl]Cl₂, the 2 Cl− ions outside the coordination sphere are ionizable and form AgCl, while the inner Cl is a ligand. Thus, 2 moles precipitate.

Ligands are named alphabetically: ammine (NH₃), aqua (H₂O), chlorido (Cl). There are 4 NH₃, 1 H₂O, and 1 Cl in the complex. Co’s oxidation state is +3 (since [Co(NH₃)4(H₂O)Cl]2+ balances 2 Cl−). Name: tetraammineaquachloridocobalt(III) chloride.

Let the oxidation state of Pt be x. Each Cl− has a charge of −1, and there are 6 Cl− ligands, contributing −6. The overall charge is −2. Thus, x + (−6) = −2, so x = +4.
