A 3.0 × 10 mL sample of 0.50 M CH3COOH is titrated with 0.50 M NaOH. The pH at the half equivalence point is measured to be 4.74.
a) Determine the volume of 0.50 M NaOH that must be delivered to reach the half equivalence point.
b) The pH at the half equivalence point is measured to be 4.74. Find pKa for CH3COOH.
c) Identify the species that have the highest concentrations in the solution being titrated at the half equivalence point.
