What Is The Chemical Composition Of Silver Iodide?

Silver iodide is a chemical compound that consists of one silver atom and one iodine atom, with a formula AgI. Its molecular weight is 234.77 g/mol.

In terms of its crystal structure, silver iodide belongs to the cubic crystal system and has a wurtzite (hexagonal) structure at temperatures below 147 °C. It is a yellowish-white crystalline solid, which is insoluble in water but soluble in ammonia and potassium iodide solutions.

Silver iodide is often used as a cloud-seeding agent to induce precipitation in clouds. When dispersed into the atmosphere, it can act as a nucleus for water droplets to form around, leading to precipitation.

The compound is also used in photography, as its light-sensitive properties make it ideal for creating photographic emulsions. Silver iodide can be synthesized by combining aqueous solutions of silver nitrate and potassium iodide, which will result in a precipitate of silver iodide.
