Hydrogen fluoride (fluorane) is an inorganic compound with chemical formula H F. It is a very poisonous, colorless gas or liquid that dissolves in water to yield hydrofluoric acid .
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water.Solutions of HF are colorless, acidic and highly corrosive.A common concentration is 49% (48-52%) but there are also stronger solutions (e.g. 70%) and pure HF has a boiling point near room temperature.
HF is miscible with water (will dissolve in any proportion), while the other hydrogen halides have large solubility gaps with water. Hydrogen fluoride and water also form several compounds in the solid state, most notably a 1:1 compound that does not melt until −40 °C (−40 °F), which is 44 degrees Celsius (79 degrees Fahrenheit) above the ...
Water fluoridation, which is the act of adding fluoride to drinking water to reach a recommended level, is designed to help prevent cavities, the ADA explains. The ADA refers to this as a “cost ...
Hydrogen fluoride is a highly toxic gas produced by lithium ion battery fires that can cause severe respiratory damage as well as skin and eye burns. The EPA did not plan to conduct soil or water ...
Hydrogen fluoride (HF), like water, is a polar molecule, and due to its polarity it can dissolve many ionic compounds. At atmospheric pressure , its melting point is 189.15 K (−84.00 °C), and its boiling point is 292.69 K (19.54 °C); the difference between the two is a little more than 100 K. HF also makes hydrogen bonds with its neighbor ...
The first place in America to receive fluoridated water was Grand Rapids, Michigan, in 1945, when residents there became guinea pigs for the theory that boosting existing natural fluoride levels ...
This neutralization reaction forms hydrogen fluoride (HF), the conjugate acid of fluoride. In aqueous solution, fluoride has a pK b value of 10.8. It is therefore a weak base, and tends to remain as the fluoride ion rather than generating a substantial amount of hydrogen fluoride. That is, the following equilibrium favours the left-hand side in ...
