The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well. The ferric chloride test can be used to detect metabolites in urine in case of inborn error of metabolism such as phenylketonuria. In addition,the Ferric Chloride test can be used to detect salicylates in urine after an aspirin overdose.1
Background information-
pH pH is characterized by the measure of Hydrogen ion concentration in a substance.The pH scale usually runs from 1 to 14. A pH of zero suggesting that the substance is exceptionally acidic and, that there is a high concentration of Hydrogen ions in the substance.Conversely, a pH of 14 implies that the substance is exceedingly basic with a low concentration of Hydrogen ions. …show more content…
