WebA solution containing appreciable amounts of a weak conjugate acid-base pair is called a buffer solution, or a buffer. Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added ( Figure 14.14 ). WebYou can use the Henderson-Hasselbalch equation on strong acids but we'll have a situation where [A-] >> [HA]. However it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%.
