CHEMISTRY LAB PERCENTAGE OF ACETIC ACID IN VINEGAR By Titration INTRODUCTION: The quality of acid in a sample of vinegar nay be Distilled vinegar was used in the titration portion of the lab. The percentage mass of acetic acid in the vinegar is found from the mass of acetic acid and the mass of Run 1 Run 2 Run 3. Percentage (w/v) of ethanoic acid in vinegar = 0.856 x 60 x 100 / 1000 = 5.14% Volume of vinegar _____ _____ _____ Procedure. Cancel Please give proper reference to my IB student, Azam if you use his material. Please give proper reference to my IB student ,Eileen if you use her material. a 5mL sample of vinegar should then have .00420 moles of each vinegar type Actual percentage of acetic acid determined by converting each equivalence point to moles of NaOH, then acetic acid (1:1 ratio) Molar mass of acetic acid and density of vinegar used to find the % mass: household, 5.24%, apple cider, 5.04%, red wine, 4.85%, white Hydrochloric acid is a corrosive, strong mineral acid with many industrial uses. The volume of acetic acid used in vinegar is comparatively small. Determination of concentration ethanoic acid in vinegar by titration method. In this laboratory exercise we will determine the percentage Acetic Acid (CH 3 CO 2 H) in Vinegar. This Site Might Help You. RESULTS and CALCULATIONS. The concentration of acetic acid in vinegar was 0.66 M, and 4.0% by weight of vinegar. Vinegar is a solution of ethanoic acid dissolved in water. Most commercial vinegar is labeled as 5% acetic acid, but can have a mass percentage of between 4.0% and 5.5% acetic acid. 0.0189 moles of acetic acid x 60.0 g of acetic acid = 1.13 g of acetic acid 1 mole of acetic acid To calculate the weight percentage of acetic acid in vinegar: 1.13 g of acetic acid x 100% = 4.52% acetic acid in vinegar 25.00 g of vinegar This final answer is what you are trying to determine in this experiment. The PERCENTAGE CONCENTRATION OF ACETIC ACID in the vinegar can be calculated as follows: The molar mass of acetic acid is 60.00 g / mole.
