As an example, let's calculate the pH of a 0.030 M solution of sodium benzoate (C 6 H 5 CO 2 Na) in water from the value of Ka for benzoic acid (C 6 H 5 CO 2 H): Ka = 6.3 x 10 -5.
May 18, 2018 · Overall, it is more effective as the pH of a system is reduced with the optimal functional range between pH 2.5 to 4.0. The antimicrobial effect is also enhanced by the presence of sodium chloride. Production. There are three methods for the commercial preparation of sodium benzoate.
In this lab, you will perform an acid/base reaction and then purify the resulting product via recrystallization. Sodium benzoate is a chemical commonly used as a food preservative. If sodium benzoate becomes protonated, it will form benzoic acid. In your prelab work, you will look up the pKa of HCl and the pKa of benzoic acid to determine if ...
