Question

What is the change observed when AgCl reacts with NH3?

Answer 1

agcl + nh3 = (Ag(NH3)2)CL

Answer 2

Answer: When white silver chloride reacts with ammonia, a colorless solution of Di-amine silver chloride.

Explanation: When the cation of electronegative non metal chlorine ($Cl^{-}$) reacts with the anion of electropositive metal silver ($Ag^{+}$), they form a compound silver chloride ($AgCl$)

The compound of silver chloride is white in appearance and has a solid state of matter.
The reaction occurs :

$Ag^{+} + Cl^{-}$⇒ $AgCl$

When the atom of nitrogen forms a covalent bond with three atoms of hydrogen, the formation of ammonia takes place.

The compound of ammonia is formed by the sharing of three electrons by the hydrogen atoms to nitrogen atom in order to complete their duplet ( Hydrogen ) and octat ( Nitrogen ) and become stable.

The bond can be represented as:

$N$≡$H$

When there is a reaction between ammonia and silver chloride, the white color of silver chloride fades and a colorless solution of di-amine silver chloride is formed.

The reaction occurs:

$AgCl +2NH_{3}$ ⇒$[Ag(NH_{3})_{2} ]Cl$

Here, the color is the main change to be visually recognized. The white color of silver chloride fades to colorless.
