WebApr 7, 2024 · An acid is defined as a donor of protons by the Bronsted-Lowry theory. According to this hypothesis, a base is a proton acceptor (or an H+ ion acceptor). Bronsted acids dissociate to release protons, resulting in a higher concentration of H+ ions in the solution. Acid ⇌ Proton + Conjugate base. WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion … route 202 in paWebIn this theory, water can be either an acid or a base; this is because it can accept a proton to form H 3 O + or donate a proton to form OH –; when a compound can act as both a Bronsted-Lowry acid or base, it is said to be amphoteric. The Bronsted-Lowry theory adds onto the Arrhenius theory. The general idea of yielding H + and OH – ions is ... strayer online classes
