WebNachweis von Phosphat - YouTube Der Nachweis von Phosphationen wird mit konzentrierter Salpetersäure, konzentriertem Ammoniak und Ammoniummolybdatlösung durchgeführt. … WebA simple qualitative method to determine the presence of phosphate ions in a sample is as follows. A small amount of the sample is acidified with concentrated nitric acid, to which a little ammonium molybdate is added. The presence of phosphate ions is indicated by the formation of a bright yellow precipitate layer of ammonium phosphomolybdate.
