1) This neutralization reaction forms hydrogen fluoride (HF), the conjugate acid of fluoride. In aqueous solution, fluoride has a p K b value of 10.8. It is therefore a weak base, and tends to remain as the fluoride ion rather than generating a substantial amount of hydrogen fluoride. That is, the following equilibrium favours the left-hand side in water: F − + H 2 O ...

Designations: Calcium fluoride is a mineral composed of CaF2. It occurs as cubic, isometric crystals and cleavable masses. When pure, it is colorless and transparent, or translucent with a glassy luster. Impurities cause color in the stone, and several varieties exhibit fluorescence.
Jul 01, 2013· In large doses, however, it can cause tooth mottling and even deterioration of bones (fluorosis). Phosphate companies historically have had scrubbers in the stacks of their chemical processing plants, but in the 1960s cases of citrus damage and fluorosis in area cattle caused regulators to tighten the restrictions on fluoride emissions.
