Practice: A 31.43 mL volume of 0.108 M NaOH is required to reach the phenolphthalein endpoint in the titration of a 4.441 g sample of vinegar. Calculate the percent acetic acid in vinegar?
Practice: A 31.43mL volume of 0.108MNaOH is required to reach the phenolphthalein endpoint in the titration of a 4.441g sample of vinegar. Calculate the percent acetic acid in vinegar?
To calculate the percent acetic acid in vinegar, we need to determine the amount of acetic acid present in the 4.441 g sample of vinegarConvert the volume of NaOH used to liters :
Volume of = 31.43 mL = 0.03143 LCalculate the number of moles of NaOH used in the titration:
Moles of =
Moles of = 0.108 M * 0.03143 L = 0.003392 moles
