"Web1) When [HA] = [A–], the logarithm becomes zero, and therefore, the pH = pKa. 2) [HA] > [A–]: If there is more acid than its conjugate base in the solution, then the pH will be smaller than the pKa ( pH < pKa) because the logarithm is a negative number. This also makes sense intuitively; more HA means more acid, and thus a lower pH. " - Ph formula with pka
