- Silver iodide is
compound with the formula
The compound is a bright yellow solid, but samples almost always
contain impurities of metallic silver that give a gray coloration.
- Silver iodide exists in four different
crystalline modifications a low-temperature cubic form with the
sphalerite structure, a hexagonal form with the wurtzite structure,
a high - temperature form with a disorder body centered cubic
structure, and a high - pressure sodium chloride type cubic
- The silver contamination
arises because AgI is highly
photosensitive. This property is exploited in
photography. Silver iodide is also used as an
- Silver iodide is so commonly used for
cloud seeding is that it is practically insoluble in water. That is,
it stays in the solid form rather than dissolving in water. This
characteristic is essential to the success of cloud seeding.
- The crystalline structure of silver
iodide closely resembles that of ice, and as such it makes a
very effective surrogate for ice as nucleating agents in the
- Initially was prepared by precipitation from solutions of
varying concentration of silver nitrate and sodium iodide.
- Silver iodide is prepared by reaction
of an iodide solution (e.g., potassium iodide) with a solution of
silver ions (e.g., silver nitrate).
- Niepce, a scientist discovered that
the vapour from iodine reacted with the silver coating to produce
silver iodide, a light sensitive compound.
