As a liquid, HF forms relatively strong hydrogen bonds, hence its relatively high boiling point. Solid HF consists of zig-zag chains of HF molecules. The HF molecules, with a short covalent H–F bond of 95 pm length, are linked to neighboring molecules by intermolecular H–F distances of 155 pm. Liquid HF also consists of chains of HF molecules, but the chains are shorter, consisting on average of only five or six molecules. huffy beach cruiser tire replacementWebHF(aq) + H 2 O(l) ¨Æ H 3 O +(aq) + F−(aq) K a = 7.2 ¥ 10 − 4 Hydrofluoric acid, HF(aq), dissociates in water as represented by the equation above.
