Characteristic
Silver iodide is an inorganic compound with the formula AgI. The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration.
Chemical formula：AgI
Molar mass： 234.77 g/mol
Appearance： yellow, crystalline solid
Odor： odorless
Density： 5.675 g/cm3, solid
Melting point： 558 °C (1,036 °F; 831 K)
Boiling point： 1,506 °C (2,743 °F; 1,779 K)
Solubility in water：3×10−7g/100mL (20 °C)
Solubility product (Ksp)：8.52 × 10 −17
Magnetic susceptibility (χ)：−80.0·10−6 cm3/mol
Crystal structure：hexagonal (β-phase, < 147 °C)
cubic (α-phase, > 147 °C)
Application
Used in medicine for its caustic, astringent and antiseptic effects. Used in photography, and in the estimation of silver. Through heterogeneous nucleation, it is used in cloud seeding, relying on its beta-AgI crystal structure being similar to that of Ice.
