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)
Tibetan silver iron 'cheese metal' casting, overlaid with this pewter and silver plating. Dependent on source, these can be either thick and robust, or attractive but easily broken due to a loose, fragile inner casting. The latter productions are therefore only suitable for small castings up to around 12 mm, or transient 'fashion' jewelry with a short lifespan. Tibetan silver Tibetan silver is used primarily in jewelry components, and is similar to pewter – an alloy of copper, and sometimes tin or nickel, with a small percentage of pure silver. Its overall appearance is of aged silver, but it can be polished
