Silver tetrafluoroborate weakly coordinating tetrafluoroborate anions. The abstraction of the halide is driven by the precipitation of the appropriate silver halide. 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
Silver chromate chromate ion and the precipitate of silver chloride already formed. When approaching the endpoint, additions of silver nitrate lead to steadily slower disappearing red colorations. When the red brownish color remains (with grayish spots of silver chloride in it) the endpoint of titration is reached. This is for neutral pH. In very acidic pH, the silver chromate is soluble, and in alkaline pH the silver precipitated as hydroxide. This reaction is used, for example, to determine the chloride level in salt water pools. Silver chromate Silver chromate (AgCrO) is a brown-red monoclinic crystal and is a chemical precursor to modern
