Silver Iodide Precipitation

AgNO3 + KI → AgI↓ + KNO3

अवलोकन

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.

रोजमर्रा का उदाहरण

Cloud seeding aircraft release silver iodide particles to induce rain, exploiting AgI's ice-like crystal structure that nucleates ice crystals.

औद्योगिक महत्व

Silver iodide is used in cloud seeding for weather modification, in photography, and as an antiseptic agent.
