Silver perchlorate is a chemical compound with the formula AgClO4. It is a useful source of the Ag+ ions, due to its great solubility.

Properties

Chemical

Silver perchlorate decomposes when heated to high temperatures, releasing oxygen.

Silver perchlorate reacts with iodine to form silver iodide and iodine perchlorate. It was hypothesized originally that this reaction would yield chlorine tetraoxide, but later experiments proved that iodine perchlorate is formed instead:[1]

AgClO4 + I2 → AgI + IClO4

Physical

Silver perchlorate is a white solid, very soluble in water. It is hygroscopic and tends to be commonly encountered as monohydrate.

Availability

Silver perchlorate is sometimes sold by chemical suppliers.

Preparation

Silver perchlorate can be made by dissolving silver metal in perchloric acid. Concentrate the resulting solution and cool it to recrystallize.

Projects

  • Catalyst in organic reactions
  • Make iodine perchlorate
  • Flash powders

Handling

Safety

Silver perchlorate is a strong oxidizer and should be handled with care.

Being a soluble silver salt, ingestion is harmful.

Storage

In closed bottles, away from moisture and flammable materials.

Disposal

Silver perchlorate can be neutralized by reducing it with metallic iron. It can also be reduced to elemental silver with many common metals, like iron, zinc. The resulting silver metal should be recycled as it is expensive.
