FAQ
Frequently Asked Questions
In the small quantities used for cloud seeding, it is considered to have negligible environmental impact. It is photosensitive and can be harmful if ingested in large amounts.
Its crystal structure is very similar to that of natural ice, allowing it to act as a nucleus around which ice crystals can form in supercooled cloud droplets.
Yes, it was a key light-sensitive component in early photographic processes like the daguerreotype and wet-plate collodion process.
AgI is the chemical formula for silver iodide, where 'Ag' is the symbol for silver (from Latin 'Argentum') and 'I' is the symbol for iodine.
