Cadmium chloride
= Cadmium chloride
{title2=$\mathrm{CdCl_2}$}
{wiki}
<Cadmium chloride> is conventionally written $\mathrm{CdCl_2}$, with cadmium in oxidation state +2. Solid and hydrated forms must be distinguished from dissolved cadmium-chloride species.
In <chemical solution>, chloride concentration can change the coordination environment around <cadmium>. A bulk formula therefore specifies overall composition without uniquely specifying every molecular or ionic species present.
