Henderson hasselbalch equation history
Web5 mrt. 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 Webthe calculation of pH relies on the Henderson–Hasselbalch equation, pH= pK a + log A HA (1) where K a is the dissociation constant of the weak acid, p K a = log K a, and …
