Ammonium Molybdate
AMMONIUM MOLYBDATE
Ammonium Molybdate is the inorganic compound that is usually encountered as the tetrahydrate., though a dehydrated form is also known. It is colorless to a white dry powder. Ammonium Molybdate” is also referred to as Ammonium Orthomolybdate, (NH4)2MoO4, and maybe several other compounds. But this is one of the common molybdenum compounds.
It is an ammonium salt composed of ammonium and molybdate ions in a 2:1 ratio. It plays a role as a poison and is incompatible with strong oxidizing agents, acids, alkali metals, and bases. Its appearance is crystalline colorless solid. It may be harmful if inhaled, causes skin and eye irritation Its crystals structure is octagonal. It is a non-flammable/non-combustible compound but in case of fire, it releases fumes of nitrogen oxides (NOx). It should be kept away from drains, surfaces, and groundwater. Solution of Ammonium Molybdate reacts with acids to form molybdic acid and an ammonium salt, and the pH value of a concentrated solution lies between 5 and 6. It is stored under a well-ventilated area and normal temperature and pressure. It is one of those acidic salts which are generally soluble in water. These salts react as acids to neutralize bases. These neutralizations generate heat rapidly.
It has several uses as listed below
- Ammonium Molybdate works as pigments, agricultural fertilizer, color lakes, and fabric fire retardant agents.
- It is served as a raw material for the production of molybdenum wire, and ceramic glazes.
- It is used in the manufacture of different molybdenum compounds.
- It has functioned in photography, ceramics, and paints.
- It is also utilized as a reagent for analysis as well as in the determination of phosphorus in analytical chemistry.
- In addition, it is a catalyst in the petrochemical industry with reaction accelerating capability.
