From this experiment, the NaOH 0.1 N volumetric 4.00 g to titrate the KHP 0.4021 g and drops phenopthalein 2 drops on titration to an end in a solution pink using NaOH to 20.28 ml rerunning taken for the concentration of aqueous NaOH was equal. This value was 0.0971 N to 0.0015 N production rate is probably due to the weight of KHP are expected to move, and in the process of titration volume of NaOH used to be more than a perfect ending.
