Silver Iodide Precipitation

AgNO₃ + KI → AgI↓ + KNO₃

Descripción general

Silver nitrate reacts with potassium iodide to form a yellow precipitate of silver iodide (Ksp = 8.5 × 10⁻¹⁷). AgI is extremely insoluble and does not dissolve in ammonia, unlike AgCl and AgBr. Its crystal structure is similar to ice, making it an excellent cloud seeding agent.
