This document provides the experimental procedure for a titration experiment involving sodium hydroxide (NaOH) and ethanedioic acid. Key steps include accurately weighing ethanedioic acid crystals, preparing standard solutions in graduated flasks, using a pipette and burette to measure volumes, transferring all solid washings to the graduated flask, using an indicator to determine the endpoint, and only adding 1-2 drops of indicator. The procedure aims to increase precision and accuracy of measurements to obtain reliable concentration values for NaOH.
