- Definition of AgI:
1.1 AgI, also known as Silver Iodide, in English is named Silver Iodide.
1.2 AgI is a chemical compound consisting of two atoms, Silver (Ag) and Iodine (I).
1.3 In the AgI molecule, the silver atom has an atomic mass of 107.8682 amu, and the iodine atom has an atomic mass of 126.90447 amu.
1.4 Regarding ion structure, AgI is an ionic compound with the cation being the silver ion (Ag+) and the anion being the iodine ion (I-).
- Properties:
2.1 Physical properties: AgI in solid form is yellow, odorless, and insoluble in water. Its natural state is solid and it is neither acidic nor basic (pH 7).
2.2 Chemical properties: AgI is very resistant to chemical impacts. It does not react with O2, does not react with water, and resists acid.

Preparation of AgI:
4.1 The preparation of AgI in the laboratory is usually performed by reacting AgNO3 with KI.
4.2 In industry, AgI is produced by dissolving iodine in a silver ammonia solution, then adding nitric acid to form AgI.
