According to the Bronsted-Lowry definition, what is the role of an acid?

• A. Accepts protons (H+)
• B. Donates protons (H+)
• C. Donates electrons
• D. Accepts electrons

Answer: (B)

According to the Bronsted-Lowry definition, an acid is defined as a substance that donates protons (H+ ions) to other substances. This perspective emphasizes the transfer of protons in acid-base reactions, distinguishing acids from bases. When an acid donates a proton, it typically transforms into a conjugate base, thus playing a key role in the dynamics of chemical reactions involved in acids and bases. This definition is fundamental in understanding various chemical equilibria and interactions in solution, as it highlights the behavior of substances in terms of proton exchange. In contrast, the roles associated with accepting protons or electrons belong to bases and reducing agents, respectively, which do not adhere to the Bronsted-Lowry characterizations of acids. Understanding this distinction is essential for applying acid-base chemistry concepts effectively.
