Acid-Base Equilibria Review Practice Exam 2024. Bronsted-Lowry theory of an acid? - correct answer An acid is a substance which can donate a proton (H+) to a base. Bronsted-Lowry theory of a base? - correct answer A base is a substance which can accept a proton (H+) from an acid. (N.B. All bases must have at least one pair of electrons to be able to accept a proton. T/F: When an acid loses a proton to a base, it forms a base itself. - correct answer True.
