Question

Refill the burette with the standardized 0.5 M NaOH solution provided. Record the initial volume of NaOH in your notebook. Dispense a 10.00 mL aliquot of vinegar into a clean, dry 150 mL beaker (do not pipet directly from the bottle). Dilute this aliquot with exactly 75.0 mL of distilled water. Add 10 drops of phenolphthalein solution. a) Determine the mass of Acetic Acid in the Vinegar solution for each of the three trials in the titration procedure. Average the results. b) Determine the mass of the vinegar solution used for each titration. The density of vinegar is about 1.005 g/mL. c) Determine the Percentage Acetic Acid in the Vinegar.
