Silver iodide Chemical Properties,Uses,Production

Description

Silver iodide (AgI) precipitates as a yellow, odor- and tasteless solid. Silver iodide acts as a very effective nucleus for the formation of ice crystals. Silver iodide has an important advantage over mercury as a subject for study of electrochemical properties of interfaces. It is also used as a solid lubricant for power contacts. It is also used as a local antiseptic.

Chemical Properties

Yellow Crystalline Powder

Physical properties

Light yellow hexagonal crystals or powder; darkens on exposure to light; density 5.68 g/cm3 ; melts at 558°C; vaporizes at 1,506°C; insoluble in water, most acids and ammonium carbonate solution; moderately soluble in concentrated solutions of alkali chloride, bromide, and thiosulfate; readily soluble in solutions of alkali cyanides, iodides and in hot concentrated hydriodic acid.

Uses

In cloud precipitation (rain-making).

Uses

Silver iodide is a yellow powder formed by the combination of a soluble iodide combined with silver nitrate. Silver iodide could also be formed by exposing metallic silver to the fumes of bromine as in the daguerreotype process. This was the primary halide used for all of the 19th century camera processes until the introduction of the silver bromide gelatin plate. With the exception of the daguerreotype, all silver iodide processes relied on physical development using a reducing agent such as gallic acid, pyrogallic acid, or ferrous sulfate, an acid restrainer, and excess silver.

Preparation

Silver iodide is prepared by adding a solution of sodium or potassium iodide to a hot solution of silver nitrate: Ag+ (aq) + Iˉ (aq) → Ag I (s) The precipitate is washed with boiling water. The preparation is done in the dark under ruby red light.
