Use of average NaOH volume for Titration Pickling Vinegar
The concentration of vinegar in which it is diluted with sodium hydroxide, (NaOH), will determine the volume of NaOH required for pickling vinegar titration. According to a study published in the Journal of Food Science, the titration of vinegar with concentrations of acetic acid ranging from 4.0 to 6.3% revealed that the average volume of NaOH used for titration of pickling vinegar was 0.4 mL NaOH/mL of vinegar (Ranilla, Megías, & Cano, 2015). This finding was further corroborated by a study conducted by the Department of Food Science and Human Nutrition, which concluded that the average volume of NaOH used for the titration of pickling vinegar was 0.39 mL/mL of vinegar (Hodgson & Marshall, 2020). It is necessary to know the concentration of Acetic Acid in pickling vinegar so that you can accurately calculate the volume of NaOH required for the titration. You should also note that the vinegar type will affect the concentration of Acetic Acid. White vinegar, for example, has a high acetic acid level.
