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)
CB military symbol system. Military symbols evolved out of the First World War from the British in part for secrecy, and to simplify reference to chemicals by something other than a chemical name. These symbols were sometimes applied as marking on weapons to indicate the agent contents. Military symbols constantly changed and had transitory definitions. For example, mustard gas was assigned the military symbol originally HS for "Hun Stuff". Later in the First World War the S in HS signified mustard gas that had about 25% solvent added to it. This was only in England, as HS was adopted as the military symbol
