PCl(5) reacts with finely divided silver...

`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

Upon heating with finely divided silver, `PCl_(5)` forms silver chloride. It dissolves in excess of `NH_(3)` to form a soluble complex.
`PCl_(5)+2Ag to 2 AgCl+PCl_(3)`
`AgCl+2NH_(3)(aq) to underset("Diammine silver(I) chloride")([Ag (NH_(3))_(2)]^(+) Cl^(-))`
