Fluoride volatility is the tendency of highly fluorinated molecules to vaporize at comparatively low temperatures. Heptafluorides, hexafluorides and pentafluorides have much lower boiling points than the lower- valence fluorides. Most difluorides and trifluorides have high boiling points, while most tetrafluorides and monofluorides fall in between.
Fluoridation does not affect the appearance, taste or smell of drinking water. [ 1 ] Water fluoridation is the addition of fluoride to a public water supply to reduce tooth decay. Fluoridated water contains fluoride at a level that is effective for preventing cavities; this can occur naturally or by adding fluoride. [ 2 ]
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Fluoride (/ ˈflʊəraɪd, ˈflɔːr -/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F−. (also written [F]−. ), whose salts are typically white or colorless.
A federal judge has ordered the U.S. Environmental Protection Agency to further regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.
The World Health Organization has set a safe limit for fluoride in drinking water of 1.5. Separately, the EPA has a longstanding requirement that water systems cannot have more than 4 milligrams ...
Experts eventually discovered that the water in Colorado Springs had unusually high levels of fluoride — up to 12 milligrams per liter. Fluoride is a mineral found naturally in rocks, which then ...
