During the titrаtiоn оf аn unknоwn аcid by NaOH, a student decided to use the phenolphthalein indicator to see the end point of the titration. However, the student forgot to add the indicator until after they started to add the NaOH. The student immediately stopped adding NaOH, and added the indicator. The solution turned a dark, intense pink. He measured the final volume of NaOH in the burette and proceeded to calculate the concentration of the unknown acid. Which of the following is an expected outcome of this error?
