Question

The final volume of buffer solution must be 100.00 mL and the final concentration of the weak acid must be 0.100 M. Based on this information, what mass of solid conjugate base should the student weigh out to make the buffer solution with a pH of 7.00? mass = ? g Based on this information, what volume of acid should the student measure to make the buffer solution? volume = ? mL

          The final volume of buffer solution must be 100.00 mL and the
final concentration of the weak acid must be 0.100 M. Based on this
information, what mass of solid conjugate base should the student
weigh out to make the buffer solution with a pH of 7.00?
mass = ? g
Based on this information, what volume of acid should the
student measure to make the buffer solution?
volume = ? mL

Step 1

Since the pH of the buffer solution is 7.00, and we know that pH = pKa + log([A-]/[HA]), where [A-] is the concentration of the conjugate base and [HA] is the concentration of the weak acid, we can infer that the pKa of the weak acid is also 7.00 (because log(1) = Show more…
