The severity usually depends on the pH and the concentration of the acid used. Retrieved from ” https: Although these compounds are related to the ordinary carboxylic acidsand therefore are weak acids, their chemical structure allows for the formation of an internal hydrogen bond between the hydrogen at the hydroxyl group and one of the oxygen atoms of the carboxylic group.
