In carrying out a titration of a potassium hydroxide solution with a standard hydrochloric acid solution, a student misread the volume on the burette. That is, the actual volume recorded was smaller than the volume required to reach the end point. How will this error affect the calculated concentration of the potassium hydroxide solution?

If the recorded volume is smaller than the actual volume, then the calculated concentration of the potassium hydroxide solution would be smaller than the actual concentration. This is because the calculated concentration is based on the assumption that the volume of acid needed to reach the end point is accurate, which is not the case in this scenario.
