Aqueous ammonia readily dissolves Ag CI ...

Aqueous ammonia readily dissolves `Ag CI` because

A

`NH_(3)` molecules readily solvate `Ag^(+)` and `Cl^(-)` ions

B

`NH_(3)` molecules abstract chloride from AgCl to from `NH_(4)Cl`

C

a soluble complex `Ag(NH_(3))_(6)^(+)` is formed

D

a soluble complex `Ag(NH_(3))_(2)^(+)` is formed

Text Solution

Verified by Experts

The correct Answer is:
D
AgCl is soluble in ammonia because it forms complex `[Ag (NH_(3))_(2)]^(+)` with ammonia. Formation of this complex make it like ionic, therefore it is soluble in aqueous ammonia.
`AgCl + 2NH_(4)OHrarrAg underset("(Highly soluble)") ((NH_(3))_(2)^(+))+H_(2)O+Cl^(-)`
