In the presence of acid, fluosilicate solutions release silicon tetrafluoride. The thermal decomposition of fluosilicates takes place with release of gaseous silicon tetrfluoride and formation of the solid fluoride. /Fluosilicates/

Air and Water Reactions:

Water soluble.

Reactive Group:

Salts, Basic

Reactivity Alerts:

Water-Reactive

Reactivity Profile:

Salts, basic, such as AMMONIUM FLUOROSILICATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Ammonium fluorosilicate reacts with water to form hydrofluoric acid, a source of fluoride ions. Unlike other halide ions, the fluoride ion 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.

Corrosivity:

Corrosive to aluminum
