[Uses]

Found in nature as horn silver, this white powder is made by the combination of a soluble chloride and silver nitrate. Silver bromide could also be formed by exposing metallic silver to the fumes of bromine as in the daguerreotype process. It is soluble in sodium thiosulfate, potassium bromide solutions, and strong ammonia. This silver halide was the first to be observed to darken spontaneously by exposure to light. Silver chloride formed the basis of the photogenic drawing, salted paper print, albumen print, collodion-chloride POP, gelatin chloride POP, and gaslight paper.

[Physical Properties]

White granular powder or cubic crystals; refractive index 2.071; darkens on exposure to light; density 5.56 g/cm3; Moh’s hardness 2.5; melts at 455°C; vaporizes at 1,547°C; vapor pressure 1 and 5 torr at 912 and 1,019°C; insoluble in water, alcohol and dilute acids; soluble in ammonia solution and concentrated sulfuric acid, alkali cyanide, ammonium carbonate; also soluble in potassium bromide and sodium thiosulfate solutions.
[Uses]

Silver chloride is used in silver plating and to obtain pure silver. The salt also finds applications in photography and optics; in photochromic glass; and in electrodes and batteries. It is used to make antiseptic silver solution. It occurs as the mineral cerargyrite.
[Preparation]

Silver chloride is prepared by slowly adding an alkali metal chloride solution to a hot solution of silver nitrate. The solution mixture is boiled:
Ag+ (aq) + Cl¯ (aq) → AgCl (s)
The precipitate is washed with hot water. The product is purified by dissolving in ammonia solution, filtering out any insoluble residues, and then adding hydrochloric acid to reprecipitate silver chloride. Preparation should be carried out in the dark in ruby red light.
