In carrying out a titration of a potassium hydroxide solution with a standard hydrochloric acıd 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?
