Correct answer
See solution below.
Step-by-step explanation
[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 2 = + 1
Ag = + 1
Oxidation state of Ag in [Ag(CN)2]
Ag + (1) 2 = 1
Ag 2 = 1
Ag = + 1
Sum of oxidation states of two silver ions in [Ag(NH3)2][Ag(CN)2] complex is 2.
Oxidation of Ag in [Ag(NH3)2]+
Ag + 0 2 = + 1
Ag = + 1
Oxidation state of Ag in [Ag(CN)2]
Ag + (1) 2 = 1
Ag 2 = 1
Ag = + 1
Sum of oxidation states of two silver ions in [Ag(NH3)2][Ag(CN)2] complex is 2.
