Sodium molybdate

Sodium Molybdate is an inorganic compound with the formula Na₂MoO₄. It is a white, crystalline powder that is soluble in water, but not in organic solvents. Sodium molybdate is used in a variety of applications, including as a corrosion inhibitor, a nutrient supplement, and a reagent in chemical analysis.

Chemical Properties

Sodium molybdate is a salt of molybdenum. It is a white, crystalline powder that is soluble in water, but not in organic solvents. The compound is stable under normal conditions, but it can decompose when heated to produce toxic fumes of sodium oxide and molybdenum.

Applications

Sodium molybdate has a wide range of applications. It is used as a corrosion inhibitor in water treatment systems, as it forms a protective passivation layer on metal surfaces. In the field of agriculture, it is used as a micronutrient supplement to correct molybdenum deficiencies in soils. In biochemistry, sodium molybdate is used as a reagent in the assay of alkaline phosphatases.

Health and Safety

Exposure to sodium molybdate can cause irritation to the eyes, skin, and respiratory tract. Ingestion can lead to symptoms such as nausea, vomiting, and abdominal pain. Long-term exposure can lead to more serious health effects, including damage to the liver and kidneys.
