6. Acid/base titration is a common method to determine the molarities of acids or bases, the molarity of certain salts can also be determined by titration. It took 22.34 mL of 0.5861 M HCI solution to neutralize 25.00 mL NaNO₂ solution. The acid- dissociation constant of HNO₂ is 4.511 × 10-¹. NaNO₂ + HCl → HNO₂ + NaCl Please answer the following questions. A What is pH of the NaNO₂ solution before titration? Hint, calculate the molarity of the NaNO₂ solution first. pH = Please provider your answer below. 0₂ ← D. A Check answer B. What is the pH when 12.78 mL of 0.5861 M HCI solution was added to the NaNO₂ solution? pH = Please provider your answer below. 0² 0₂ ( → ← t Check answer C. What is the pH when 14.39 mL of 0.5861 M HCl solution was added to the NaNO₂ solution AFTER the equivalence point? pH = (0) A Please provider your answer below. 0₂ ← → Check answer What is the pH at equivalence point at 25 °C? pH = Please provider your answer below.
