**pH, pKa, and the Henderson-Hasselbalch Equation**
https://www.thoughtco.com/the-ph-and-pka-relationship-603643

If you know either pH or pKa, you can solve for the other value using an approximation called the Henderson-Hasselbalch equation: pH = pKa + log ([conjugate base]/[weak acid]) pH = pka+log ([A-]/[HA]) pH is the sum of the pKa value and the log of the concentration of the conjugate base divided by the concentration of the weak acid.
