| | Disodium Molybdate Usage And Synthesis |
| Preparation | may be obtained as a dihydrate by evaporating an aqueous solution of molybdenum trioxide and sodium hydroxide. Heating the dihydrate at 100°C converts it to the anhydrous salt.
| | Chemical Properties | solid | | Uses | Sodium molybdate (Na2MO4) may be used as an electrolyte additive, for use in electrochemical capacitors. Addition of Na2MO4 as an electrolyte additive may result in enhanced capacitance, corrosion prevention and stabilized performance.
It may also be used as a catalyst during the manufacture of paints and dyes. | | Uses | Sodium Molybdate is used in method for preparing fermentation medium with reduced color and viscosity. | | Uses | Reagent in analytical chemistry, paint pigment,
production of molybdated toners and lakes, metal
finishing, brightening agent for zinc plating, corro-
sion inhibitor, catalyst in dye and pigment produc-
tion, additive for fertilizers and feeds, micronutri-
ent. | | Definition | ChEBI: An inorganic sodium salt having molybdate as the counterion. | | General Description | Sodium molybdate has corrosion resistant properties. On heating, it undergoes degradation and releases Na2O fumes. | | Hazard | Irritant. | | Flammability and Explosibility | Non flammable | | Agricultural Uses | Sodium molybdate (NazMoO4-2H2O), which is an
important molybdenum source, is applied along with
other fertilizers or as a foliar spray (with 39%
molybdenum). Sodium molybdate is the sodium salt of
molybdic acid. Fusing molybdenum oxide with sodium
carbonate or hydroxide makes sodium molybdate.
Molybdenum is an essential component of the enzyme
nitrate reductase which catalyzes the conversion of
nitrate (NO3-) to nitrite (NO2-). It is also a component of
the nitrogenase enzyme involved in nitrogen fixation by
root nodule bacteria of leguminous crops. Soaking seeds
in sodium molybdate solution (made with slurry or dust)
before sowing is an effective seed treatment. Sodium
molybdate, the most commonly used fertilizer supplying
molybdenum, is used as foliar spray, or in mixed
fertilizers. It is also used in seed treatment. | | Biological Activity | sodium molybdate is an acid phosphatase inhibitor. the osteoclastic acid phosphatase isoenzyme, secreted by osteoclasts, is a member of a widely-distributed class of iron-containing proteins with acid phosphatase activity. elevated plasma isoenzyme levels are associated with increased bone turnover in metabolic disease. by inhibiting this class of acid phosphatases, sodium molybdate is capable of abolishing bone resorption. in addition, sodium molybdate has been shown to stabilize the nonactivated glucocorticoid-receptor complex.1. zaidi m, moonga b, moss dw, et al. inhibition of osteoclastic acid phosphatase abolishes bone resorption. biochemical and biophysical research communications, 1989, 159(1): 68-71.2. denis m, wikström ac, gustafsson ja. the molybdate-stabilized nonactivated glucocorticoid receptor contains a dimer of mr 90,000 non-hormone-binding protein. journal of biological chemistry, 1987, 262(24): 11803-11806. | | Safety Profile | Poison by
intraperitoneal route. Moderately toxic by
subcutaneous and intravenous routes.
Experimental reproductive effects. Mutation
data reported. When heated to
decomposition it emits toxic fumes of
Na2O. See also MOLYBDENUM
