Appearance: White, crystalline powder or granules, highly soluble in water.

Chemical Formula: Na₂MoO₄·2H₂O, containing molybdate ions (MoO₄²⁻) essential for various chemical processes.

Agricultural Use: Functions as a micronutrient in fertilizers, providing molybdenum for plant growth, particularly important for legumes that rely on nitrogen fixation.

Corrosion Inhibitor: Used in industrial water treatment systems to prevent corrosion of metals by forming a protective layer on metal surfaces.

Laboratory Reagent: Frequently used in analytical chemistry and research, especially for detecting phosphates in colorimetric assays.

Biological Importance: Molybdenum is crucial for enzyme functions in both plants and animals, facilitating processes like nitrogen fixation and amino acid synthesis.

Buffer Agent: Suitable for applications that require stable pH levels, commonly used in biological and chemical buffers.
