Look up the % acetic acid on a bottle of vinegar in your cabinet or at the store. What is the percent error of your experimental determination from the actual on the bottle? If your calculated % acetic acid differs more than 15% from that on a bottle of vinegar check your calculations. If your standardized NaOH were used to titrate 20.00 mL of sulfuric acid (H2SO4), a diprotic acid, what concentration of sulfuric acid would you determine if 24.66 mL of the NaOH solution were required by the titration? First write the balance equation for the reaction so as to use the correct stoichiometry in the calculation. Hint: watch part II of the Carolina titration video: Setting up and Performing a Titration.
