OVERVIEW of the EXPERIMENT

1. STANDARDIZATION of the NaOH Solution
   • weigh out "KHP" standard.
   • Titrate to phenolphthalein end-point.
   • Molarities of the NaOH obtained from Duplicate titrations should agree to within 1%.
   • Calculate the average Molarity of the NaOH solution.
2. Determining the w/v% Acetic Acid in Vinegar
   • Pipet out 5.00 mL of the vinegar solution,
   • Titrate to the phenolphthalein end-point with the standardized NaOH solution.
   • Duplicate titrations should agree to within 0.10 mL.
   • Use your Average Molarity of the NaOH and the titration data to calculate the w/v% of acetic acid in your Vinegar UNKNOWN.
3. Determining the Ascorbic Acid content of a Vitamin C tablet
   • Weigh the tablet on an Analytical Balance.
   • Soak the tablet in your titration flaskto soften.
   • Break up the tablet with a stirring rod.
   • Titrate with your standard NaOH solution to the phenolphthalein end-point.
   • Calculate the mg of Ascorbic Acid in your tablet.
