Autoignition =Silver perchlorate is the
chemical compound with the formula AgClO4. This white solid forms a monohydrate and is mildlydeliquescent . It is a useful source of the Ag+ ion, although the presence ofperchlorate presents risks.olubility
Silver perchlorate is noteworthy for its solubility in aromatic solvents such as
benzene (52.8 g/L) andtoluene (1010 g/L).F. Brezina, J. Mollin, R. Pastorek, Z. Sindelar. "Chemicke tabulky anorganickych sloucenin" ("Chemical tables of inorganic compounds"). SNTL, 1986.] In these solvents, the silver cation binds to the arene, as has been demonstrated by extensive crystallographic studies on crystals obtained from such solutions. [E. A. Hall Griffith, E.

Similar to
silver nitrate , silver perchlorate is an effective reagent for replacinghalide s ligands with perchlorate, which is a weakly ornon-coordinating anion . The use of silver perchlorate in chemical synthesis has declined due to concerns about explosiveness of its salts. Other silver reagents aresilver tetrafluoroborate , and the relatedsilver trifluoromethanesulfonate andsilver hexafluorophosphate .References
