Ammonium molybdate tetrahydrate

CAS number: 12054-85-2
Molecular weight: 1235.86
Molecular formula / chemical symbol: (NH4)6.Mo7O24.4H2O

Description

Colorless or light yellow-green monoclinic crystals. The relative density of 2.498. Soluble in water, acid and alkali, insoluble in alcohol. The loss of one water of crystallization, when heated to 90℃190°C is decomposed into ammonia, water, and molybdenum trioxide. Place the air weathering, losing part of the ammonia.

USES

For the determination of phosphate, alkaloids, arsenate and lead reagents. Also used in the photographic industry, chromatography the analysis agent as well as ceramic glaze.
