When a metal rod M is dipped into an aqueous colourless concetrated solution of compound N, the solution turns light blue. Addition of aqueous NaCl to the blue solution gives a white precipitate O. Addition of aqueous `NH_3` dissolves O and gives an intense blue solution.
Q. The final solution contains.

A

`[Ph(NH_3)_4]^(2+)` and `[ClCl_4]^(2-)`

B

`[Al(NH_3)_4]^(3+)` and `[Cu(NH_3)_4]^(2+)`

C

`[Ag(NH_3)_2]^(o+)` and `[Cu(NH_3)_4]^(4+)`

D

`[Ag(NH_3)_2]^(o+)` and `[Ni(NH_3)_6]^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
C

`(ii) Cu^(2+)+AgCl overset(NH_(3))to[Ag(NH_(3))_(2)]^(o+)+underset("Deep blue")([Cu(NH_(3))_(4)]^(2+))`
