Silver(I) chloride

염화은 C화학적 특성, 용도, 생산

화학적 성질

Silver chloride, AgCl, is a white,granular powder that darkens on exposure to light,finally turning black.It exists in several modifications differing in behavior toward light and solubility in various solvents. Soluble in ammonium hydroxide, concentrated sulfuric acid, and sodium thiosulfate and potassium bromide solutions, very slightly soluble in water, can be melted, cast, and fabricated like a metal. Derived by heating a silver nitrate solution and adding hydrochloric acid or salt solution. The whole is boiled, then filtered. This must take place in the dark or under a ruby-red light. Used in photography,photometry and optics, batteries, photochromic glass,silver plating,production of pure silver, and as an antiseptic. Single crystals are used for infrared absorption cells and lens elements and as a lab reagent

용도

In silver plating, in making antiseptic silver preparations.

용도

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.

용도

Used in photographic films, to coat and silver glass, as an antiseptic, and to absorb infrared light in lenses.

정의

White, granular powder; darkens on exposure to light, finally turning black. Exists in several modifications differing in behavior toward light and in their solubility in various solvents.Soluble in ammonium hydroxide, concentrated sulfuric acid and sodiu

위험도

As for silver.

Purification Methods

Recrystallise it from conc NH3 solution by acidifying with HCl, filtering off the solid, washing it with H2O and drying it in a vacuum. It is soluble in NH3 and should be kept in the dark.
