Silver perchlorate is the chemical compound with the formula AgClO₄. This white solid forms a monohydrate and is mildly deliquescent. It is a useful source of the Ag⁺ ion, although the presence of perchlorate presents risks.

[edit] Solubility

Silver perchlorate is noteworthy for its solubility in aromatic solvents such as benzene (52.8 g/L) and toluene (1010 g/L).^[1] In these solvents, the silver cation binds to the arene, as has been demonstrated by extensive crystallographic studies on crystals obtained from such solutions.^[2]^[3] It is also amazingly soluble in water, up to 500 g per 100 ml of water.

[edit] Related reagents

Similar to silver nitrate, silver perchlorate is an effective reagent for replacing halides ligands with perchlorate, which is a weakly or non-coordinating anion. The use of silver perchlorate in chemical synthesis has declined due to concerns about explosiveness of perchlorate salts. Other silver reagents are silver tetrafluoroborate, and the related silver trifluoromethanesulfonate and silver hexafluorophosphate.
