🤓 Based on our data, we think this question is relevant for Professor Staff's class at UTSA.
Recall the Henderson-Hasselbalch equation:
• the ideal buffer is when the amount of conjugate base is equal to the amount of the weak acid.
[conjugate base] = [weak acid]
pKa = pH
The pKa of acetic acid CH3COOH is 4.76. A buffer solution contains CH3COOH and CH3COONa and has a pH of 4.76 and a total acetate concentration (acid and base forms) of 0.400 M. What is the concentration of CH3COOH?
