Nathan Pike Wednesday 6PM Bethany Wigington Experiment #7 Introduction: The purpose of this lab was to determine the percentage of acetic acid in vinegar through the use of acid-base titration and also to determine the strength of a neutralizing antacid. In the beginning of this lab, it would be important to standardize a solution of NaOH. This is because the molarity of the NaOH is most likely slightly less than when it initially measured due to the reactivity with CO 2 in the air. This reaction causes the concentration of NaOH to be slightly more acidic. With this being said, the NaOH could be standardized through titration using HCL and then solving for the exact concentration of NaOH. NaOH(aq) + HCL (aq) NaCL(aq) + H 2 O(l) Net ionic: H + (aq) + OH - (aq) H 2 O(l) The percentage of acetic acid in vinegar was determined through use of acid-base titration. The moles of NaOH were calculated and then converted to moles of CH 3 COOH. After that the molarity of CH 3 COOH was determined and then was divided
