Conjugate base of benzoic acid
WebConjugate Acids of Bases The conjugation of acids and bases has been discussed earlier. After losing a proton, the acid species becomes the conjugate base. A base and its protonated partner also form a conjugated acid-base pair. These relationships have been represented by H + + B a s e = C o n j u g a t e a c i d o f B a s e + WebSodium benzoate is a salt of the conjugate base, the OBz - or benzoate ion. Whenever sodium benzoate dissolves in water, it dissociates into its ions. The benzoate ion then acts as a base toward water, picking up a …
