Therefore, it is a weak acid. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. melting point of metals during smelting. 9 4. 4 10. Chemical Reactions of Fluorine Reaction With Air. In moist air it reacts with water to form also-dangerous hydrofluoric acid. 1. At normal temperature , it forms oxygen 2. c. How many grams of N2F4 can be produced from 225g F2? Hydrofluoric acid is used to etch grooves in glass because it reacts with the silica (SiO2(s)) in glass. Fluorine is the most reactive and the most electronegative of all the elements. It is the lightest halogen. It is called fluorine. 8 3. The reaction of fluorine with ammonia produces dinitrogen tetrafluoride and hydrofluoric acid. 3 7. Fluorine is a pale yellow, diatomic, highly corrosive, flammable gas, with a pungent odor. Because of its extreme reactivity, fluorine does not occur uncombined in nature. The estimated value for HF in the table can be compared to the experimental value: Experimental value: 5.6 x 10-4 mol dm-3; Estimated value: 1.6 x 10-3 mol dm-3 First discovered by Henri Mossain in 1886. 2 2. Located at Group 17 and Period 2 of the periodic table. 1. It is so reactive that metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas. It reacts violently with water to produce oxygen and the extremely corrosive hydrofluoric acid. With hydrogen it forms hydrogen fluoride gas, whose water solution is called hydrofluoric acid. 7 Reaction With Water. At higher temperature, it forms ozone 3. By contrast, the estimated K a for hydrofluoric acid is small. 10 9. 1 6. Fluorine reacts with water to produce Hydrogen Fluoride(HF) and Oxygen(O2).2 H2O + 2 F2 ----> 4 HF + O2 F2(g) + NH3(g) „³ N2F4(g) + HF(g) a. It is far too reactive to be found in elemental form. How many grams of NH3 are required to produce 4.65g HF? Fluorine is not particularly reactive towards with oxygen or Nitrogen, but it reacts with moisture in air and forms oxygen (O 2) 2 F 2 (g) + 2 H 2 O (g) → O 2 (g) + 4 HF (g). What is the coefficient of hydrofluoric acid in the balanced equation for the reaction? Hydrofluoric acid only ionizes to a limited extent in water. 5 5. The products of the reactions are aqueous silicon tetrafluoride and water. Fluorine reacts with water to produce Oxygen (O 2) and Ozone (O 3) 2 F 2 (g) + 2 H 2 O (l) → O 2 (g) + 4 HF (aq) Or 6 8. Fluorine also called super halogen due to its highly reactive nature reacts violently with water to produce oxygen , ozone or oxoflouride 1. 2. b. If you have 66.5g NH3, how many grams of F2 are required for complete reaction? Fluorine. Fluorine reacts with most inorganic and organic compounds.
