Lab 8: Antacid Analysis – Discussion The purpose of this lab was to use acid-base titration to determine the percent acetic acid in vinegar, as well as determining the tablets’ ability to neutralize. Part one of the lab was skipped over. In part two, .3M NaOH was used to titrate vinegar until a faint pink color was reached. OH-(aq) + HC2H3O2(aq) -> H2O(l) + C2H3O2-(aq) By using a burette, the amount used was determined; calculations were done to get the percent

Unformatted text preview: acetic acid. Part three called for first adding .3M HCl to an antacid solution until it turned red – indicating consumption of any base – and then was titrated with .3M NaOH. CaCO3(s) + 2 H(aq) --> [Ca]2+(aq) + CO2(g) + H2O(l) The results were within range of the given accepted results. No errors were known to occur....
