Three trials are conducted with varying masses and volumes to ensure accuracy. Each trial reflects the mass of KHP used, as well as initial and final readings from a buret used to measure the NaOH solution. The volume of NaOH used in each trial is the difference between the final and initial buret readings. The average concentration of NaOH calculated from these trials is given as 0.0988 M.This exercise demonstrates the titration process in a laboratory setting and provides insight into how to calculate solution concentrations accurately.
