Similar to acetic acid, benzoic acid is a weak acid (HA) and is a commonly used as antimicrobial preservative in food and beverages, especially in carbonated beverages Suppose 10.00-mL of 0.5000 M benzoic acid (C6H5COOH) is titrated with 0.2000M NaOH. Ka for benzoic acid is 6.3 x 10-5 . What is the pH after addition of 35.00 mL of NaOH to the benzoic acid solution?
