Consider the following sequence of reactions.

The change from B to C involves the reaction

Options

A. `[Hg(NH_(3))_(4)]^(2)+ 2H^(+) +Cr^(-) to Hg(NH_(2))CI darr +3NH_(4)^(+)`
B. `[Pb(NH_(3))_(4)]^(2+)+4H^(+) +2C^(-) to PbCl_(2) darr +4NH_(4)^(+)`
C. `[Pb(OH)_(4)]^(2-) +4H^(+) +2C^(-) to PbCl_(2) +4H_(2)O`
D. `[Ag(NH_(3))_(2)]^(2+) + 2H^(+) +Cl^(-) to AgCl darr +2NH_(4)^(+)`

Answer

D

Explanation

`[Ag(NH_(3))_(2)]^(+2) + 2H^(+) +Cl^(-) to AgCl darr +2NH_(4)^(+)`
