This lab we set out to find the percent of acetic acid in common vinegar. We standardized a solution of NaOH with the acid potassium hydrogen phthalate (KHP) in a titration to determine the molarity of NaOH. Next we used the standard NaOH solution to determine the percent of acetic acid in vinegar. Lastly we diluted 10mL vinegar with 90 mL distilled water to make a 100mL solution, add our KHP and titrate as usual. We used this dilution to compare. The lab was pretty fun.
