Arrhenius acids and bases make up a class of compounds, which include many of many of our most common compounds and laboratory reagents. ... According to the Henderson-Hasselbalch equation, pH = pKa + log [base/acid] If there are equal moles of weak acid and the base, NaOH at the half-equivalency point during this lab, then the pKa is equal to the solution's pH value. ... The weak acid, HA ionizes according to the equation: HA  H+ + A- The ionization will occur until equilibrium is established. ...
