Reactivity AlertsWater-Reactive
Reactivity Profile
Fluorosilicates react with water to generate hydrofluoric acid and silicic acid, and are thus sources of soluble fluoride ions. Unlike other halide ions, fluoride is quite reactive, acting as a weak base and participating in some unique reactions. In particular, fluorides react strongly with compounds containing calcium, magnesium, or silicon ions, which means that solutions containing soluble fluorides are corrosive to both living tissue and glass. Hydrofluoric acid can cause severe chemical burns and is one of the few materials that can etch glass. It is also a toxic gas in its anhydrous form.
Air and Water ReactionsSlightly soluble in water. Forms heavy clouds with moist air, decomposed by water into silicic acid and hydrofluoric acid [Merck 11th ed. 1989].
