In case of HF when HF reacts with H2O it will act as an Acid and donates its H+ (hydronium ion) so, it will act as an acid, lets look here : HF + H2O <-----> F- + H3O +

Vätefluorid, även känt som fluorväte eller fluoran är en kemisk förening mellan väte och fluor med formeln HF. Ämnet är en gas med kokpunkt något under

On its own, or pure water (H20) does not conduct electricity very well. That said however, when certain substances as in this case, Hydrogen Fluoride-are dissolved in water, the solution does Hydrogen fluoride: HF (g)-272.677-272.724: ± 0.049: kJ/mol: 20.006343 ± HF (g) → HF (aq, 400 H2O) → Return; Note: The listed uncertainity of the reaction Water can form three-dimensional network of hydrogen bonds whereas HF & NH3 can only form Chains. The trend of the strength of the hydrogen bonding of HF (10 KCal/mol) > H2O (7 KCal/mol) > NH3 (2 KCal/mol). Hoever, the extent of Hydrogen bonding is H2O > HF > NH3. Answer to In the equation HF + H 2O H 3O + + F − H2O is a base, and HF is its conjugate acid. H2O is an acid, and HF is the conj HF and H2O. c. H3O+ and H2O. b. F- and H3O+.

but if you are interested here is a brief overview The factor in play here is Hydrogen bonding the stronger the hyd bonding the hig Here, a combined experimental and theoretical study of the dissociation dynamics of the tetra-atomic FH2O system is presented, providing snapshots of the F + H2O → HF + OH reaction. Photoelectron-photofragment coincidence measurements of the dissociative photodetachment (DPD) of the F(-)(H2O) anion revealed various dissociation pathways along different electronic states.

H2O and H3O(-) ∆Hf° H2O (l) = − 285.8 kJ / mole ∆Hf° CO2 (g) = − 393.3 kJ / mole What is the standard heat of formation of methane, ∆Hf° CH4 (g), as calculated from the data above? (A) −210.0 kJ/mole (B) −107.5 kJ/mole (C) −75.8 kJ/mole (D) 75.8 kJ/mole (E) 210.0 kJ/mole Mixtures of hydrogen fluoride (HF) and water (H 2O) play an important role in many industrial processes.1 Much of the practical value of the HF/H 2O solution arises from its aggressive behavior. Thus, the vapor mixture is used for etching in the processing of semi-conductors, and the solution is used in pickling of steel.
