WebThe weak acid present in our buffer solution is acetic acid. And at 25 degrees Celsius, the pKa value of acetic acid is equal to 4.74. The acetate anion is our conjugated base and it has a concentration of 0.33 molar, so we can plug that into the Henderson-Hasselbalch equation, and the concentration of our weak acid is also 0.33 molar.
