Chem 253 Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium benzoate. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic pH. Rather than benzoic acid‚ sodium benzoate is used because it is generally soluble in most aqueous solutions but benzoic

experiment is to determine the pH values of acids‚ bases‚ and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution‚ or containing an atom that can accept a pair of electrons from a base (McKinley‚ Dean O’Loughlin‚ & Stouter Bidle‚ 2016). Bases are water-soluble and are harsh tasting compounds
