`Ag_(2)S +NaCN rarr (a)`
(a) `+Zn rarr (d)`
(b) is a metal. Hence `(a)` and `(b)` are

A

`Na_(2)[Zn(CN)_(4)],Zn`

B

`Na[Ag(CN)_(2)],Ag`

C

`Na[Ag(CN)_(4)],Ag`

D

`Na_(3)[Ag(CN)_(4)],Ag`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(Ag_(2)S+4NaCN,,rarr,,2Naunderset((a))[[Ag(CN)_(4)]]+Na_(2)S),(2Naunderset((a))[Ag(CN)_(4)],,overset(Zn)rarr,,(Agdarr)^(-)+Na_(2)underset((b))underset((Impure))[Zn(CN)_(4)]):}`
