At higher temperature, it forms ozone 3. By contrast, the estimated K a for hydrofluoric acid is small. 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). 1. The reaction of fluorine with ammonia produces dinitrogen tetrafluoride and hydrofluoric acid. It is the lightest halogen. 10 9. melting point of metals during smelting. 1 6. b. Fluorine reacts with most inorganic and organic compounds. With hydrogen it forms hydrogen fluoride gas, whose water solution is called hydrofluoric acid. Therefore, it is a weak acid. 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 Fluorine reacts with water to produce Hydrogen Fluoride(HF) and Oxygen(O2).2 H2O + 2 F2 ----> 4 HF + O2 In moist air it reacts with water to form also-dangerous hydrofluoric acid. Located at Group 17 and Period 2 of the periodic table. 9 4. Fluorine. Fluorine also called super halogen due to its highly reactive nature reacts violently with water to produce oxygen , ozone or oxoflouride 1. Hydrofluoric acid is used to etch grooves in glass because it reacts with the silica (SiO2(s)) in glass. 3 7. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. It is far too reactive to be found in elemental form. 2 2. Because of its extreme reactivity, fluorine does not occur uncombined in nature. 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. Hydrofluoric acid only ionizes to a limited extent in water. Fluorine is the most reactive and the most electronegative of all the elements. 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 At normal temperature , it forms oxygen 2. First discovered by Henri Mossain in 1886. (Balance the equation with the smallest possible whole number coefficients.) 6 8. c. How many grams of N2F4 can be produced from 225g F2? 5 5. Chemical Reactions of Fluorine Reaction With Air. It is called fluorine. Reaction With Water. 8 3. 2. 4 10. 7 1. Fluorine is a pale yellow, diatomic, highly corrosive, flammable gas, with a pungent odor. What is the coefficient of hydrofluoric acid in the balanced equation for the reaction? If you have 66.5g NH3, how many grams of F2 are required for complete reaction? In 1529, Georgius Agricola described fluorine as an additive used to lower the . The products of the reactions are aqueous silicon tetrafluoride and water. F2(g) + NH3(g) „³ N2F4(g) + HF(g) a. How many grams of NH3 are required to produce 4.65g HF? It reacts violently with water to produce oxygen and the extremely corrosive hydrofluoric acid.
