WebBy definition, the chemical formulas of conjugate particles must differ by exactly and only one proton, H +1, and should otherwise be identical to one another. Additionally, Brønsted-Lowry acids and bases are used to prepare solutions and, therefore, must be represented on the left side of the arrow in a given acid/base equation. HF is diatomic in the gas-phase. 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.
