Common Phases
pKa is the negative logarithm of the acid dissociation constant; A high
pKa value indicates a weak acid; The lower the
pKa, the stronger the acid; To calculate
pKa, use the Henderson-Hasselbalch equation; Protonation occurs when an acid donates a proton to a base, decreasing its
pKa value; Deprotonation occurs when a base accepts a proton from an acid, increasing its
pKa value.
