To calculate the pH of a buffer system, we can use the Henderson-Hasselbalch equation: pH = pKa + log([A-]/[HA]) where pKa is the dissociation constant of the weak acid, [A-] is the concentration of the conjugate base, and [HA] is the concentration of the weak acid.

You can see that hydroxide ion is a stronger base than ammonia (NH 3), because ammonium (NH 4 +, pK a = 9.2) is a stronger acid than water (pK a = 14.00). The stronger the conjugate acid, the weaker the conjugate base. short tulle dress dress
