Explanation:
Benzoic acid or benzene-carbonic-acid is a monobasic aromatic acid, moderately strong, white crystalline powder, very soluble in alcohol, ether, and benzene, but poorly soluble in water (0.3 g of benzoic acid in 100 g of water at 20 °C).
Benzoic acid has the advantage that it does not affect the odor or taste of the soft drink, if used in small quantities. The preserving quality of benzoic acid is based on its activity to delay the multiplication of several groups of microorganisms, which, however, are not killed by this product. The low solubility of benzoic acid in water complicates its application in products containing large amounts of water. Therefore, the water-soluble salt sodium benzoate is used.
