QJEEM21Chf249: JEE Main 2021 Chemistry - Class 12 JEEM21Chf249 Solution: The sum of oxidation states of two silver ions in [Ag(NH 3 ) 2…

[Ag(NH₃)₂][Ag(CN)₂] complex dissociates into [Ag(NH₃)₂]⁺ and [Ag(CN)₂].

Oxidation of Ag in [Ag(NH₃)₂]⁺

Ag + 0 $\times$ 2 = + 1

Ag = + 1

Oxidation state of Ag in [Ag(CN)₂] ^$-$

Ag + ( $-$ 1) $\times$ 2 = $-$ 1

Ag $-$ 2 = $-$ 1

$\Rightarrow$ Ag = + 1

$\therefore$ Sum of oxidation states of two silver ions in [Ag(NH₃)₂][Ag(CN)₂] complex is 2.
