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. WebA base is a substance that contains a hydroxide group and dissociates to produce a hydroxide ion in aqueous solution. QUESTION 13 Which of the choices is the Lewis definition of acids and bases?
