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)
Heart (symbol) heart shape was used to represent the heart-shaped fruit of the plant Silphium, a plant possibly used as a contraceptive Many species in the parsley family have estrogenic properties, and some, such as wild carrot, were used to induce abortion. Silver coins from Cyrene of the 6–5th BC bear a similar design, sometimes accompanied by a silphium plant and is understood to represent its seed or fruit. It is likely that the heart symbol was found in devotion to God. The symbol appears as one rights themselves up, after having prayed with one's head to the ground. The hands form
