Purpose : The purpose of this lab is to use titrimetry in order to determine the molarity of NaOH and acetic acid. Procedure : KHP and NaOH Titration: A buret was cleaned out with water and then rinsed with NaOH The buret was filled with NaOH to just below zero mL o Record the starting volume to 2 decimal places The KHP was prepared o A weighing paper was placed on balance and the balance was zeroed o About 1-2 grams KHP was added and weighed to three decimal places o The solid KHP was transfered to an Erlenmeyer flask and water was added to dissolve completely o 2 drops of phenolphthalein were added Titration of KHP o 1-2 mL NaOH were added to KHP solution and swirled o More NaOH was added until pink started to stay show in the KHP solution for longer periods of time o The volume of NaOH was recorded when the pink first stayed persistently Repeat 2 times Acetic Acid and NaOH Titration: 10 mL of the unknown acetic acid was added, by pipet, to a flask
