Physical Properties Of Benzoic Acid. The variable group also called the R group or side chain determines the identity and many of the properties of a specific amino acid. Which compound is more soluble in waterbenzoic acid or sodium benzoate. As we will learn when we study acid-base chemistry in a later chapter carboxylic acids such as benzoic acid are relatively weak acids and thus exist mostly in the acidic protonated form when added to pure water. Although the addition of BA can extend the shelf life of drinks and prevent nutritional losses.
