Titration of Acetic Acid
Titration for Acetic Acid in Vinegar
Purpose:
The Primary Purpose of this Experiment is to Determine the Percent Content of Acetic Acid in a Household Bottle of President’s Choice Vinegar, using Titration Techniques. In addition, a Secondary Purpose for this Experiment that Derives Directly from the Primary Purpose is to Gain Hands On Experience in Titration Techniques, as a Vital Tool in our Quest to Understanding the Chemical Aspect of the World around Us.
Procedure
Conducting a Titration is the Process of Applying a Balanced Chemical Equation to Determine the Volume of a Solution with an Unknown Molarity or Concentration that is Need to React with a Pre-Determined Amount of a Second Solution of a Known Molarity and Concentration. In order to Achieve a Proper Titration, however, a great deal of measuring, preparation, and precision was required from me; beginning with arranging the equipment so that the Stop Cock Tip of the Test Tube located in the Elevated Clamp Handle is located approximately one to two centimeters above the beaker where the Color Change in the Titration Indicator, in this case Phenolphthalein, is to be observed. I then proceeded to Pour and Measure 9.9 mL of 0.5 Sodium Hydroxide Solution, taking care to allow a few drops of the Sodium Hydroxide Solution to drip into the Beaker, in order to Ensure a More Accurate Reading of the Volume of Solution Used Once the Experiment was Preformed. Once the Beaker was rinsed with Distilled water and the Initial Volume of Sodium Hydroxide was Recorded, the Experiment proceeded by Pouring and Measuring 5 mL of President’s Choice Vinegar into the Beaker and Subsequently adding two drops of the Titration Indicator, Phenolphthalein to the Beaker. Now Came the Reaction Portion of the Experiment, where I took care to Open the Stopcock with Such a Steady Flow that it would Add Only One Drop of Sodium Hydroxide ever Two to Three Seconds, while Simultaneously Counting and Keeping Track of How Many Drops of
