Silver tetrafluoroborate Silver tetrafluoroborate Silver tetrafluoroborate is an inorganic compound with the chemical formula AgBF. It is a white solid that dissolves in polar organic solvents as well as water. In its solid state, the Ag centers are bound to fluoride. Silver tetrafluoroborate is prepared by the reaction between boron trifluoride and silver oxide in the presence of benzene. In the inorganic and organometallic chemistry laboratory, silver tetrafluoroborate, sometimes referred to "silver BF-4", is a useful reagent. In dichloromethane, silver tetrafluoroborate is a moderately strong oxidant. Similar to silver hexafluorophosphate, it is commonly used to replace halide anions or ligands with the
Silver carbonate Silver carbonate Silver carbonate is the chemical compound with the formula AgCO. Silver carbonate is yellow but typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, like most transition metal carbonates. Silver carbonate can be prepared by combining aqueous solutions of sodium carbonate with a deficiency of silver nitrate. Freshly prepared silver carbonate is colourless, but the solid quickly turns yellow. Silver carbonate reacts with ammonia to give the explosive fulminating silver. With hydrofluoric acid, it gives silver fluoride. The thermal conversion of silver carbonate to silver metal proceeds via formation of
