What conditions can we use the HH equation?

Question: Under what conditions can we use the Henderson equation to calculate the pH if we're not told in the question that there is a buffer involved? How do we know if a solution contains a buffer or not?

Answer: The Henderson-Hasselbalch equation is used under the condition of weak acid and a salt or a weak base and a salt. Both of these are buffer solutions.
