A 20.00 mL of 0.200 M of monoprotic weak acid (HA) solution is titrated with 0.160 M of a KOH solution. When 12.50 mL of the KOH is added to the weak acid, the pH of the solution is 5.26. Calculate the pKa of the weak acid.

Step 1
In this scenario, a weak acid (HA) is being titrated with a strong base (KOH). At the point where 12.50 mL of KOH is added, the pH of the solution is 5.26. We need to calculate the pKa of the weak acid. Show more…

A 0.25-mol sample of a weak acid with an unknown pKa is combined with 10.0 mL of 3.00 M KOH, and the resulting solution is diluted to 1.500 L. The measured pH of the solution is 3.85. What is the pKa of the weak acid?
When 16.24 mL of 0.064 3 M KOH were added to 25.00 mL of 0.093 8 M weak acid, HA, the observed pH was 3.62. Find pKa for the acid.
