Silver perchlorate Silver perchlorate Silver perchlorate is the chemical compound with the formula AgClO. 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. It is used as a catalyst in organic chemistry. Silver perchlorate is created by heating a mixture of perchloric acid with silver nitrate. Alternatively, it can be prepared by the reaction between barium perchlorate and silver sulfate, or from the reaction of perchloric acid with silver oxide. Silver perchlorate is noteworthy for its solubility in aromatic solvents such as benzene (52.8 g/L)
Silver perchlorate and toluene (1010 g/L). In these solvents, the silver cation binds to the arene, as has been demonstrated by extensive crystallographic studies on crystals obtained from such solutions. It is also amazingly soluble in water, up to 500 g per 100 mL of water. 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. Silver
