It occurs in nature as horn silver as ore.
Preparation
Agcl is obtained by adding any soluble chloride to silver nitrate solution.
AgNO3 + KCl → AgCl + KNO3
White ppt
The ppt is washed, collected and then dried.
Properties
- It is white amorphous solid insoluble in water.
- AgCl is light sensitive compound and turns violet and finally to black on exposure to light.
Action of NH3 solution
AgCl dissolves in NH3 solution by forming a soluble diamine complex.
AgCl + NH4OH → Ag (NH3)2
di-amine silver (I) chloride.
(soluble complex compound)
Action of KCN solution:
Agcl dissolves in KCN solution forming a soluble potassium argento cyanide complex.
Agcl + KCN → K [Ag (CN)2] + KCl
Potassium argento cyanide
Uses
AgCl is used in making photographic film and paper.
