Description of key information

Additional information

Hexafluorosilicic acid will rapidly dissociate and hydrolyse in the environment fo form fluoride and silicate and react to form other fluorine-containing compounds. The behaviour of fluoride in water is dependent on pH and mineral content. Fluoride is deposited to sediment as insoluble complexes and is essentially immobile in soil due to its incorporation into insoluble complexes. Inorganic silicates are environmentally ubiquitous and are not considered further.
