# What is the formula for the ionic compound copper bromide containing the Cu^+ ion?

Jun 6, 2018

$\frac{1}{2} B {r}_{2} + {e}^{-} \rightarrow B {r}^{-}$
And thus $\text{cuprous bromide}$ is formulated as $C u B r$, A NEUTRAL SALT...
On the other hand $\text{cupric bromide} \equiv C u B {r}_{2}$...here we gots $C {u}^{2 +}$...
