Note: There is no "algebra" in the table below. Just a starting concentration of HA and then it is decreased step-wise by a set increment. That increment is the amount that dissociates and then appears as H+ and A–. Since all the concentrations are known, pH, percent ionization, and the value for Q are easily calculated and listed.
The concentration is and the increment is .
| [HA] | [H+]=[A-] | pH | Q or K | %ion |
