A student wished to determine the percent of acetic acid in commercial vinegar products. Brand X was selected. Three 20.0mL volumes were titrated with a 2.20mol.L sodium hydroxide solution until the indicator phenolphthalein turned pink. the density od acetic acid is 1049.2kg.m-3. the data gathered in the experiment is recorded below. Calculate the volume percent od acetic acid in vinegar.
Initial burette reading Vi= 0.00mL
Volume reading first trial titration V1= 8,82mL
Volume reading second titration V2= 16,84mL
Volume reading third titration V3= 24,08mL
Concentration of the NaOH 2.20mol.L
Volume of vinegar 20.0mL
