`PCl_(5)` reacts with finely divided silver on heating and a white silver salt is obtained , which dissolves on adding excess aqueous `NH_(3)` solution. Write the reactions involved to explain what happens.

Text Solution

Verified by Experts

`PCl_(5)` on reaction with finely divided silver produced silver halide.
`PCl_(5)+2Ag to2AgCl+PCl_(3)`
`AgCl` on further reaction with aqueous ammonia solution produces a soluble complex of `[Ag(NH_(3))_(2)]^(+)Cl^(-)`
`AgCl+2NH_(3)(aq)to underset("Soluble complex")([Ag(NH_(3))_(2)]^(+))Cl^(-)`
