Detailed explanation-1: -Solid silver iodide is preferred as a nucleator for artificially stimulated rain because its crystal lattice parameters are close to those of ice, and for that reason are more effective than other salts in causing small ice crystals in clouds to melt.
Detailed explanation-2: -Silver iodide is also used as an antiseptic and in cloud seeding. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Detailed explanation-3: -It is possible to cause artificial rain by throwing electrified sand or silver iodide from an aeroplane and thus, coagulation the mist hanging in air. AgI helps in artificial rain because : Q. The clouds consist of charged particles of water dispersed in the air.
