Натрия молибдат

Химические свойства

solid

Использование

Sodium Molybdate is used in method for preparing fermentation medium with reduced color and viscosity.

Определение

ChEBI: An inorganic sodium salt having molybdate as the counterion.

Общее описание

Sodium molybdate has corrosion resistant properties. On heating, it undergoes degradation and releases Na₂O fumes.

Опасность

Irritant.

Сельскохозяйственное использование

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.

Профиль безопасности

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 COMPOUNDS.
