No, benzoic acid is not a strong acid. Benzoic acid is a weak organic acid with a pKa of 4.20, meaning that it dissociates only partially in water to produce hydrogen ions (H+) and benzoate ions (C6H5COO-). The equilibrium constant for this dissociation reaction is very small, indicating that the majority of benzoic acid molecules remain undissociated in solution. Strong acids, on the other hand, completely dissociate in water, releasing all of their protons and producing a much higher concentration of hydrogen ions. Some common examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3).
