Results (Sodium Hydroxide Standardization – successful trial only) (35 points)
NOTE: KHP contains no phosphorous. Its formula is given in the laboratory directions along with
its molar mass.
Results (Acetic Acid Content of Vinegar – successful trials only) (35 points)
Use the value determined by all students in your lab group for the molarity of the sodium hydroxide to
complete the Vinegar Titration table.

Questions
1. Show or explain your calculation for determining Measured % Acetic Acid in vinegar sample.
You may incorporate a scan of your handwritten calculations if you prefer. (20 points)
2. If you misread the procedure and added 100 mL of distilled water to the solid KHP rather than 50
mL of water (Procedure 1.5), how would this affect the concentration of sodium hydroxide
solution that you measured? Explain
iefly. (10 points)
