Web8 nov. 2024 · The Henderson-Hasselbalch equation is as follows: pH= pKa + log [ A− ]/ [HA] On simplifying the above equation for half equivalence point: pH = pKa So, the pH is equal to the acid dissociation constant. Since the acid dissociation constant for hydrofluoric acid is given, the pH at the half equivalence point can be calculated as follows: WebAnd this is where the Henderson household back equation comes into play because we'll need to use it to calculate the pH of weak acid solutions. And this is an especially important point for biochemistry because most biological acids are actually weak acids. And so that shows why the Henderson Hasselbach equation is important for biochemists. Now.
