Stewarts acid base balance theory
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. WebThe Stewart approach models the complex chemical equilibrium system known as acid–base balance. Stewart introduced the term "strong ion difference" or [SID] to mean …

WebJan 30, 2024 · In this theory, an acid is a substance that can release a proton (like in the Arrhenius theory) and a base is a substance that can accept a proton. A basic salt, such as Na + F -, generates OH - ions in water by taking protons from water itself (to make HF): F − ( aq) + H2O ( l) ⇌ HF ( aq) + OH −.
