The sum of oxidation states of two silver ions in Ag NH 3 2 Ag ( CN ) 2 complex is _____ .

$$\begin{gathered} \left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]\left[\mathrm{Ag}(\mathrm{CN}{)}_2\right]\to {\left[\mathrm{Ag}{\left({\mathrm{NH}}_3\right)}_2\right]}^{+} + {\left[\mathrm{Ag}(\mathrm{CN}{)}_2\right]}^{-} \\ ( {\mathrm{Ag}}^{+1}) ( {\mathrm{Ag}}^{+1}) \end{gathered}$$

Sum of oxidation states of two silver ions = 1 + 1 = 2
