18. Aqueous Equilibrium

What is the pH of a solution after adding 4.3 mL of a strong acid beyond the equivalence point in a titration with a strong base?

Which of the following indicators is most suitable for use in the titration of hypobromous acid (HBrO, pKa=8.7) with a strong base?

Referring to the table below, select an indicator for use in the titration of C6H5NH2 (pKb=9.41) with a strong acid. Which indicator would be most appropriate?

Based on the titration curves of a 1 M solution of a weak acid with a strong base and a 1 M solution of a strong acid with the same base, what is the estimated pKa of the weak acid?

Given the following data: Volume of HA used = 9.19 mL, Volume of NaOH at equivalence point = 8.42 mL, pH at equivalence point = 8.66, and Concentration of NaOH = 0.1471 M, what is the pKa of the acid HA?
