Henderson Hasselbalch Calculator

Enter the conjugate base, acid [HA], and dissociation constant into the calculator to calculate the pH of a solution.

Henderson Hasselbalch Formula

The following formula is used to calculate the pH of a solution using the henderson hasselbalch equation.

pH = Kₐ + log([A⁻]/[HA])

  • Ka is the acid dissociation constant
  • A- is the molar concentration of the base in molars
  • HA is the molar conenctration of the acid in molar

pH is a measure of the solutions acidity of a solution.
