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.
