It occurs in nature as horn silver as ore.
Agcl is obtained by adding any soluble chloride to silver nitrate solution.
AgNO3 + KCl → AgCl + KNO3
The ppt is washed, collected and then dried.
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] (1 + 2H2O)
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
AgCl is used in making photographic film and paper.
