Description
A colorless, fuming liquid that is available as an aqueous solution. In water, SiF4 and HF combine to form fluosilicic acid. It is a strong acid that will attack Glass and stoneware. Dilute solutions (1-2%) are used for sterilizing bottles, disinfecting copper and brass vessels, as well as for killing fungus on wood, masonry, and Plaster. Fluosilicic acid is also used for fluoridating water, cleaning Leather, and for hardening Cement, and Lime.
Synonyms and Related Terms
fluorosilicic acid; hydrogen hexafluorosilicate; hexafluosilicic acid; hydrosilicofluoric acid; hydrofluosilicic acid; silicofluoric acid;
