Ammonium Molybdate

Ammonium Molybdate is an odourless crystalline compound ranging in colour from white to yellow-green that has a solubility of 43 g/100 cc in cold water. Ammonium molybdate decomposes at 190°c boiling temperature & losses 1 water @ 90°c at freezing temperature. Its chemical formula is as follows: (NH4)6Mo7O24.4H2O.

It is also called molybdic acid hexammonium salt tetrahydrate, ammonium molybdate tetrahydrate, and ammonium heptamolybdate tetrahydrate.

Ammonium molybdate is used in various sectors:

  • Used as catalyst in manufacturing certain colour pigments
  • To decorate ceramics
  • In chemical analysis to find the presence of phosphates, arsenics, lead
  • In the chemical industry as a source of molybdenum ions.
  • Pharmaceutical
  • Other fields

Molybdic Acid

Molybdic Acid is a white or slightly yellow colour powder that largely consists of an ammonium molybdate compound. Practically used for the determination of phosphorous / phosphate and lead, it is graded as a reagent & technical acid. Sparingly soluble in cold & more in hot water, it is also mixes with some of the ammonium and other fixed alkalines.

Sodium Molybdate

Sodium Molybdate is an odorless compound with a small white scales and flakes appearance that has a melting point of approx. 687° C (1269° F). Available with a specific gravity of 3.28 @ 18° C (64.4° F), it emits toxic metal fumes when heated to be decomposed. Soluble in 84 g/100 g water @ 100°C (212° F), sodium molybdate should be preserved to avoid moisture, heat, flames, ignition sources, and incompatibles. Sodium Molybdate acts aress an excellent inhibitor & is extensively used as :

  • Production of molybdate toners & colours
  • Die & Pigment production
  • Metal Furnishing

Sodium Tungstate

Sodium Tungstate, Na2WO4, a tungstate of sodium, is useful as a source of tungsten. It is prepared from tungsten ores used to manufacture tungsten by reducing it.

It is often found as the dihydrate, Na2WO4-2H2O. This salt is soluble in water and is a moderately strong oxidizing agent, but finds no common use in the chemistry laboratory. Like the molybdate, the deep-coloured complex tungstate(VI,V) is formed on reducing the compound with a very mild reducing agent, such as complex organic compounds. It is also thought to be a possible inhibitor of protein-tyrosine phosphatase (PTPase). It is also sometimes used as a fireproofing agent.

Ammonium Sulfate

Ammonium Sulfate, (NH4)2SO4, is an inorganic salt with a number of commercial uses. It contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions.
