Experimental parameters of ammonium molybdate tetrahydrate

English name: Ammonium molybdate tetrahydrate; Ammonium heptamolybdate tetrahydrate; Molybdic acid ammonium salt tetrahydrate; Ammonium heptamolybate; Hexaammonium heptamolybdate tetrahydrate Other names: ammonium molybdate tetrahydrate; ammonium molybdate tetrahydrate; ammonium heptamolybdate; :12054-85-2(NH4) 6Mo7O24·4H2O=1235.86 Grade: 4N trait: colorless to slightly green or yellowish crystal. It is easily weathered in the air and loses a part of ammonia. When heated to 90 ° C, one molecule of water of crystallization is lost, and at 190 ° C, it decomposes into ammonia, water and molybdenum trioxide. Dissolved in 2.3 parts of water, almost insoluble in ethanol. The pH of the 5% aqueous solution is 5 to 5.5. The relative density is 2.498. Toxic, half-lethal dose (rat, oral) 333mG/kG. Irritating. Uses: biochemical research. Determination of phosphate, arsenate, lead, alkaloids. Molybdenum blue method was used to determine the phosphorus content of soil and plants. The activity of inorganic phosphorus and alkaline phosphatase in serum was measured. Determination of silicon and phosphorus in steel. For ceramic glaze preservation: RT
