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)
Non-logical symbol over the signature mentioned above is the ordered group of integers. Its domain is the set formula_1 = {…, –2, –1, 0, 1, 2, …} of integers. The binary function symbol + is interpreted by addition, the constant symbol 0 by the additive identity, and the binary relation symbol < by the relation less than. Outside a mathematical context, it is often more appropriate to work with more informal interpretations. Rudolf Carnap introduced a terminology distinguishing between logical and non-logical symbols (which he called "descriptive signs") of a formal system under a certain type of interpretation, defined by what they
