A 25.00 mL аliquоt оf the weаk аcid sоlution (HA) was titrated with 0.0985 M NaOH(aq) using both an indicator and a pH meter. Ka (HA), is 1.65 x10-5. A total of 34.34 mL of 0.0985 M NaOH(aq) was required to reach the equivalence point 1. Calculate the molarity of the acid solution. (4 pts) 2. Calculate the pH of the acid solution (Hint: use the RICE table). (4 pts) 3. Calculate the pH and [A-]at the half-equivalence point. (3 pts) 4. Calculate the pH at the equivalence point of the titration. (Hint: use Kb for hydrolysis of A- anion and RICE table). (3 pts) 5. Suggest an appropriate indicator for titration. Explain your choice. (2 pts) 6. Calculate the pH of the solution after 20.00 mL of 0.0985 M NaOH(aq) was added. (Hint: find moles of HA and A- and use Henderson-Hasselbalch equation).
