18. Aqueous Equilibrium

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?

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

What is the pH at the equivalence point for the titration of 20.0 mL of 0.500 M acetic acid (HC2H3O2) with 0.350 M potassium hydroxide (KOH), given that the Ka for acetic acid is 1.8 × 10^-5?

What is the pH of the solution after titrating 25.00 mL of 0.22 M HC2H3O2 with 25.00 mL of 0.22 M NaOH?
