Hexaammonium molybdate Usage And Synthesis
Physical Properties Colorless, monoclinic crystal; density 2.276 g/cm3; decomposes on heating; soluble in water (decomposes); also soluble in acid; insoluble in alcohol and liquid ammonia.
Uses Ammonium molybdates are used to prepare high purity grade molybdenum metal powder, sheet, or wire; for colorimetric analysis of phosphates and arsenates; for decorating ceramics; and as catalysts.
Preparation Ammonium molybdate is prepared by treating molybdenum oxide with excess ammonia in an aqueous solution. The crystals are obtained after evaporation of water.
MoO3 + 2NH3 + H2O → (NH4)2MoO4
Reactions Decomposes on heating or on treatment with alkalies; reacts with lead chloride and other metal salts to form their metal molybdates:
(NH4)2MoO4 + PbCl2 → PbMoO4 + 2NH4Cl
Reacts with phosphates or arsenates to form ammonium phosphomolybdate (NH4)3PO4•12MoO3, or ammonium arsenomolybdate, (NH4)3AsO4•12MoO3.
Chemical Properties colourless to light green crystalline solid
General Description White to greenish-yellow solid. Sinks and mixes with water.
Air & Water Reactions Water soluble.
Reactivity Profile Salts, basic, such as Hexaammonium molybdate , are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
Health Hazard Inhalation causes irritation of nose and throat. Contact with eyes causes irritation.
Fire Hazard Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire.
Agricultural Uses Ammonium molybdate, (NH4)6MO7O24·2H2O is an important molybdenum fertilizer. It is an ammonium salt of molybdic acid and contains about 50% molybdenum.
Ammonium molybdate is generally mixed with NPK fertilizers, depending on the crop requirement (generally 50 to l000 gm per ha). The fertilizer is also applied as a foliar spray, but coating or soaking seeds with ammonium molybdate is the easiest method of application, which requires very little fertilizer.
