The calculator uses the Henderson Hasselbalch equation. This equation connects pH, pKa, acid concentration, and base concentration.
The formula is:
pH = pKa + log10([Conjugate Base] / [Weak Acid])
The pKa value represents acid strength. A lower pKa indicates a stronger acid. The concentration ratio determines the final pH value.
Enter the pKa value of your weak acid. Provide the conjugate base concentration. Enter the weak acid concentration.
