Benzoic acid C6H5COOH is an organic compound containing a carboxylic acid functional group -COOH attached to a benzene ring. The carboxylic acid functional group is known to be acidic due to the presence of a hydrogen atom bonded to an electronegative oxygen atom. This hydrogen atom can be easily lost as a proton H+ in an aqueous solution, resulting in the formation of a carboxylate anion C6H5COO- .Based on its chemical structure and functional groups, benzoic acid is predicted to be acidic.
