WebJan 22, 2024 · A Brønsted-Lowry base is a proton (hydrogen ion) acceptor. When a Brønsted acid HA dissociates in water, it increases the concentration of hydrogen ions in the solution, H +; conversely, Brønsted bases dissociate by taking a proton from the solvent (water) to generate OH -. Acid dissociation. (4.1.1) H A ( a q) ⇌ A ( a q) − + H ( a q) +.
