Internal Assessment Determination of the concentration of ethanoic(acetic) acid in vinegar
Aim
To determine the concentration of ethanoic acid, in vinegar.
Introduction
Vinegar contains a small percentage of ethanoic acid, . This experiment intends to find out the concentration of the vinegar against a standard solution of sodium hydroxide (NaOH) of concentration through acid-base titration. The equation of the reaction between ethanoic acid and sodium hydroxide is as follows:
The end point of the titration process can be determined and the amount of reactants used can be measured. Using the values obtained from the titration and also the chemical equation as a reference, the concentration of ethanoic acid in the vinegar can be determined through stochiometric calculations.
Phenolphthalein indicator solution will be used in this acid-base titration
Variables:
