WebBuffer solution two also consists of acidic acid and the acetate anion. However, in this case, both concentrations are 0.0250 molar. So buffer solution one has a higher concentration of both acidic acid and the acetate anion. Let's calculate the initial pH of both buffer solutions using the Henderson-Hasselbalch equation. WebHenderson-Hasselbalch equation. Acid-Base and Solubility Equilibria Notes page 2 of 7 ⇒ In solving common ion and buffer problems, assume [HA] eq and [A-] eq are equal to their initial concentrations. (That is, the approximation method is valid for these problems.) ⇒ A special situation occurs when [HA] ...
