What is a Brønsted-Lowry acid?
A Brønsted-Lowry acid is a substance that can donate a proton (H⁺ ion) to another substance. In the context of the IB Chemistry course, it is important to understand that this definition of an acid extends beyond traditional acids like hydrochloric acid or sulphuric acid to include any chemical species capable of proton donation. The Brønsted-Lowry theory focuses on the transfer of protons and provides a broader framework than the Arrhenius definition, which is limited to acids in aqueous solutions. This theory applies to reactions in all states of matter and is essential for explaining acid-base reactions where the roles of acids and bases are determined by their ability to donate or accept protons, respectively. Understanding this concept is crucial for exploring acid-base equilibria and the various roles acids can play in chemical reactions.
