WebThe naming of molybdates generally follows the convention of a prefix to show the number of Mo atoms present. For example, dimolybdatefor 2 molybdenum atoms; trimolybdatefor 3 molybdenum atoms, etc.. Sometimes the oxidation state is added as a suffix, such as in pentamolybdate(VI). The heptamolybdate ion, Mo 7O6− WebAmmonium molybdate tetrahydrate (AMT) is a molybdenum salt. Study of its extraction from nickel-molybdenum (Ni–Mo) ore by direct hydrometallurgical method has been reported. [ 1] Its degradation by combustion to form elemental molybdenum powder using metallic reducers has been investigated. [ 2] Anwendung

A measured amount of boiler water is poured into a mixing … WebA simple spectrophotometric method has been developed for the determination of phosphate dissolved in soil and water. The method is based on the formation of phosphomolybdate with added ammonium molybdate followed by reduction with hydrazine in acidic medium. Orthophosphate and molybdate ions conden …
Web2.1 Ammonium molybdate and antimony potassium tartrate react in an acid medium with dilute solutions of phosphorus to form an antimony-phospho-molybdate complex. This complex is reduced to an intensely blue-colored complex by ascorbic acid. The color is proportional to the phosphorus concentration.
