Henderson-Hasselbalch Equation: Derivation, Applications, Formula

WebMar 5, 2024 · The Henderson-Hasselbalch equation defines the relationship between pH and the ratio of A c − and H A c. It is as follows (1.5.1) p H = p K a + log ( [ A c −] [ H A c]) This simple equation defines the relationship between the pH of a solution and the ratio of Ac- and HAc in it. The new term, called the pKa, is defined as (1.5.2) pKa = − log Ka WebIn 1916, Hasselbalch expressed Henderson’s equation in logarithmic terms, consistent with the logarithmic scale of pH, and thus the Henderson-Hasselbalch equation was born. … pitchfork writing https://amythill.com
