You are trying to determine the percentage of acetic acid in vinegar by titrating a sample of the vinegar with a standardized NaOH solution. Why is bromcresol green not a good choice for an indicator for this titration? If you do use bromcresol green as an indicator, will your result for the percentage of acetic acid in vinegar be too high or too low? What would be a better choice for an indicator for this titration? Why is your choice better?

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
