WebNov 6, 2024 · According to Lowry-BrØnsted acid-base theory based on the transfer of protons between H+ donors (acids) and H+acceptors (bases), changes in either the mass balance of H+or the donation/release of H+between a donor- acceptor pair within a given compartment are responsible for an alteration in the H+concentration (13, 85). WebWhen approaching the analysis of disorders of acid-base balance, physical chemists, physiologists, and clinicians, tend to focus on different aspects of the relevant phenomenology. The physical chemist focuses on a quantitative understanding of proton hydration and aqueous proton transfer reactions that alter the acidity of a given solution.
