WebOct 7, 2024 · A buffer is an aqueous solution that has a highly stable pH. A buffering agent is a weak acid or weak base that helps maintain the pH of an aqueous solution after adding another acid or base. If you add an acid or a base to a buffered solution, its pH will not change significantly. WebHowever 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%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. Hope that helps.
