# What are the common oxidation states of tin metal?

May 15, 2017

$\text{Stannous ion}$ is $S {n}^{2 +}$, and $S n C {l}_{2}$ is $\text{stannous chloride}$ (insert $\text{Game of Thrones}$ reference here!).
$\text{Stannic ion}$ is $S {n}^{4 +}$, and $S n C {l}_{4}$ is $\text{stannic chloride}$, which is a volatile liquid.
Likewise, $\text{titanic chloride}$, and $\text{titanous chloride}$ are $T i C {l}_{4} \left(l\right)$, and $T i C {l}_{2} \left(s\right)$ respectively. But don't get confused. $T i$ represents titanium metal, and $S n$ represent $\text{stannum}$, i.e. $\text{tin}$.
