Dennis Uzar 4/20/11 Erick Passiack Acetic Acid In Vinegar A titration is a technique which determines the number of moles of a substance in a given volume of solution. In, Acetic Acid In Vinegar, samples of vinegar were titrated in order to determine the number of moles of acetic acid that are present in vinegar. To execute a titration a reagent of which the molar concentration is known is reacted with the solution that is being tested, in this case .205M of NaOH was added to the vinegar which is the unknown. NaOH was slowly added to the vinegar until it reached its equivalence point which was signaled by a pink color change caused by the phenolphthalein that was added before the titration began. It was absolutely imperative to keep the pink color change as light as possible in order to yield accurate results. Once the equivalence point was reached the number of moles of NaOH that was added to the vinegar was calculated by taking the amount of NaOH added (40.8mL) converting to liters then multiplying by the molarity of NaOH (.205M) which yielded .008364 mol NaOH.
