Is ammonium molybdate hazardous?
Ingestion: May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. Inhalation: May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Causes chemical burns to the respiratory tract.
What is ammonium molybdate used for?
Ammonium molybdate is a source of molybdenum that exists in several hydrate forms. It is intravenously administered as an additive to solutions for Total Parenteral Nutrition (TPN). Molybdenum is an essential element that is present in enzymes including xanthine oxidase, sulfite oxidase, and aldehyde oxidase.
What is ammonium molybdate?
Ammonium orthomolybdate is the inorganic compound with the chemical formula (NH4)2MoO4. It is a white solid that is prepared by treating molybdenum trioxide with aqueous ammonia. Upon heating these solutions, ammonia is lost, to give ammonium heptamolybdate ((NH4)6Mo7O24. 4H2O).
What PPE is required for handling ammonium molybdate reagent?
Hand protection : Wear protective gloves. Eye protection : Chemical goggles or face shield. Skin and body protection : Wear suitable protective clothing. Respiratory protection : Wear appropriate mask.
Is ammonium molybdate flammable?
Ammonium Molybdate itself does not burn. POISONOUS GASES ARE PRODUCED IN FIRE, including Ammonia and Nitrogen Oxides. Use water spray to keep fire-exposed containers cool.
How do you dispose of ammonium molybdate?
Product/containers must not be disposed together with household garbage. Do not allow product to reach sewage system or open water.It is the responsibility of the waste generator to properly characterize all waste materials according to applicable regulatory entities (US 40CFR262. 11).
How do you use ammonium molybdate?
Molybdate reagent: a) dissolve 1.0 g of ammonium molybdate in 100 ml of 2 M H2SO4; b) dissolve 0.10 g of hydrazine sulphate in 100 ml of water. Immediately before use, mix 10 ml of solution a) with 10 ml of solution b) and dilute the solution with water to 100 ml.
What test uses ammonium molybdate?
Ammonium orthomolybdate is used as a corrosion inhibitor. Ammonium tetrathiomolybdate is used for the analysis of chloride in a solution. Ammonium heptamolybdate is used as a reagent for testing the presence of phosphates, silicates, arsenates, and lead in the aqueous solutions.
Is ammonium molybdate and ammonium heptamolybdate same?
190 °C (decomp.) It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although “ammonium molybdate” can also refer to ammonium orthomolybdate, (NH4)2MoO4, and several other compounds. It is one of the more common molybdenum compounds.
What is the Colour of ammonium molybdate?
Ammonium molybdate $(NH4)3MoO4$ is a white solid and the ammonium phosphomolybdate is obtained as a yellow precipitate. It is used for estimation of PO−34 in a given analytical experiment and in soil. Therefore, from the above discussion, it is evident that ammonium phosphomolybdate is yellow in colour.
Is molybdate flammable?
