A buffer solution is prepared by dissolving 1.000 g of sodium acetate (CH3COONa) into 100.00 mL of a 0.100 Msolution of acetic acid. Then 3.00 mL of a 3.00 M solution of sodium hydroxide is added to the acetic acid/sodium acetatebuffer solution. What is the pH of the solution after adding NaOH? Round your answer to 2 decimal places.Note: Reference the Ka of acids at 25 °C table for additional information.

Since KOH is a strong base and completely dissociates into K and OH in an aqueous solution, the molarity of OH equals the molarity of KOH. Finally, rearrange the dilution equation (M₁ V₁M₂V₂) to solve for the initial volume (Vi).
