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
The silver contamination arises because AgI is highly photosensitive. This property is exploited in silver-based photography. Silver iodide is also used as an antiseptic and in cloud seeding.
