In an experiment, a chemist prepared two different buffer solutions. For each one, calculate the molarity of the acid and the salt (conjugate base) in the solution. Then use the Henderson-Hasselbalch equation to calculate the expected initial molarity of each buffer.
a) Buffer #1: 20.0 mL of 0.200 M acetic acid solution and 10.0 mL of 0.200 M NaOH solution.
b) Buffer #2: 20.0 mL of 0.200 M acetic acid solution and 15.0 mL of 0.200 M NaOH solution.
