Henderson-Hasselbalch Calculator
Calculate pH using the Henderson-Hasselbalch equation for chemistry enthusiasts.
What is the Henderson-Hasselbalch Calculator & How does it work?
The Henderson-Hasselbalch equation is a fundamental tool in acid-base chemistry, used to calculate the pH of a buffer solution. It relates the pH to the pKa of the acid and the concentrations of the conjugate base and acid.This equation is particularly useful in biochemistry and environmental science for understanding how buffers maintain pH levels.
pH = pKa + \log\left(\frac{[A^-]}{[HA]}\right)
pH = the pH of the solution
pKa = the negative logarithm of the acid dissociation constant
[A–] = concentration of the conjugate base
[HA] = concentration of the weak acid
pKa = the negative logarithm of the acid dissociation constant
[A–] = concentration of the conjugate base
[HA] = concentration of the weak acid
