10.2: Brønsted-Lowry Definition of Acids and Bases

WebIn the Brønsted–Lowry definition of acids and bases, an acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Brønsted–Lowry acid loses a proton, a conjugate base is formed. Similarly, when a Brønsted–Lowry base gains a proton, a conjugate acid is formed.

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. hypertrophic uncovertebral jointsWebYes, though to be more specific, it is the H+ ions that indirectly cause an acidic food to taste sour.
