To a 25.00 mL volumetric flask, a lab technician adds a 0.375 g sample of a weak monoprotic acid, HA , and dilutes to the mark with distilled water. The technician then titrates this weak acid solution with 0.0923 M KOH . She reaches the endpoint after adding 44.93 mL of the KOH solution. After the technician adds 15.35 mL of the KOH solution, the pH of the mixture is 5.73. Determine the p?a of the weak acid.
