Experimental Procedure

1. Using a 600.0 mL volumetric flask, make a 0.5 M solution of NaOH. 

2. Using a 10.00 mL graduated cylinder, place 10.00 mL of vinegar in a clean Erlenmeyer flask. Record the precise volume of the vinegar used. Add 20.00 mL of distilled water to the flask using a graduated cylinder. Add 2-3 drops of phenolphthalein to the flask.

3. Set up the buret and titration set up as instructed and place a white piece of paperunder the Erlenmeyer flask. Place about 100mL of NaOH of known molarity in a beaker and carry it to your table. Prime the buret with a small amount of NaOH.Fill the buret with NaOH as instructed. Make sure that you allow the NaOH to run through the buret until the volume reading is 0.00mL and there are no air bubbles trapped in the tip of the buret.

4. Record the volume of NaOH in the buret appropriately. Use a white piece of paper placed against the buret to read the bottom of the meniscus each time you take a volume reading. Begin titrating NaOH into the Erlenmeyer. As you approach the end point of the titration, the pink color will disappear more slowly.At a certain point, one drop of NaOH will cause the entire solution to turn to a faint PERMANENT pink color. This is the end point of the titration. Record the volume of NaOH used to reach this end point. The volume should be recorded with two digits behind the decimal (proper significant figures).
